New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc

inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It

3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.

link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid

- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

- Once GrClipStack is enabled everywhere, it means GrReducedClip and

GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of

2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It

GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid

- When a new save record is pushed on the stack, older elements are
