- Once we add all the missing intrinsics, the locally defined ones
can go away.
- Having the default interpreter vector width match the raster pipeline
is a huge perf win.

3 new getters:
- localToWorld
- localToCamera
- localToDevice (same as total-matrix)
The current tracking minimizes overhead, by using a computed inverse to
produce the localToWorld/Camera. This can be change as needed in the
future (more precision, but more memory/overhead), but for now is
sufficient to try out the new APIs.

Propose a standard way to talk about the camera (etc) in SkCanvas:
- client provides 3 matrices: viewport, projection, camera
- canvas->concat(viewport * projection * camera * invert(viewport)
- camera and projection are taken straight from the textbook for 3D
- "viewport" means a matrix that transforms +-1 square about the origin
to the clients working canvas. A simple way to describe it is:
"specify the area-of-interest with a rectangle and z_scale"
Expose the ctm as a 44 from canvas for now. Likely we will add these
3 new matrices to canvas, and each may have a getter.

That would get categorized as perspective, but in reality that matrix

categorized as affine (seen as simpler/faster).

To facilitate this, the GrQuadBuffer::Iter's local GrQuads that are
modified on each next() are now allowed to be operated on for the AA
inset/outsetting. Previously this required additional GrQuads on the
stack to hold the results, and additional guards for accessing localQuad()
when the entry didn't have actual coords.
With this change, a 2D op should have its device and src GrQuads' Ws
set to 1 once, and then they are completely ignored for all iteration
and tessellation, without any more redundant initialization. In all
likelihood we won't see the needle move on powerful platforms, but may
help lower end devices.

The intent is to allow the creation of a MakeFontMgrRunIterator which
uses the passed font's typeface as the primary typeface, but uses a
given family name and style as for the request for fallback fonts. This
allows the user to provide the actual request for the primary typeface
as opposed to making a request based on the resolved primary typeface
(which may not be the right thing to do).
To support this, the selection of language for fallback is also added.
Since this information is already in the language iterator, this change
makes the font iterator the lowest priority iterator for consume,
allowing the font iterator to rely on the current value of the language
iterator to provide the language.
In order to allow these changes to be exercised, this also adds a few
generic 'Make' methods for bidi and script. These new methods will use
the best available implementation. These are needed since the most
capable implementations may not always be available (such as on our
testing ios builds).

Previously the pixel data passed to the client was only valid during

Now we pass an object to the callback and the pixel lifetime is tied
to the lifetime of that object.
The object may be holding a GPU transfer buffer mapped. We don't assume
that the object will be released on the direct GrContext thread. So
when the object is destroyed it posts a message to a new type,
GrClientMappedBufferManager, hanging off the direct context. The direct
context will periodically check for messages and unmap and then unref
buffers so that they can be reused. Currently this is done in
GrContext::performDeferredCleanup() and GrDrawingManager::flush().
The old API is kept around for backwards compatibility but it is
reimplemented as a bridge on top of the new mechanism.
Also a utility function to SkImageInfo is added to directly make a new
info with a specified dimensions rather than passing the width and
height separately to makeWH().

The DrawDeviceWithFilter function used to rely on SkImageFilter's
applyCTMForBackdrop, which would create a new DAG and use an
SkMatrixImageFilter node to account for the transformation. However,
that filter is really meant to perform a transformation prior to the
CTM matrix. Abusing matrix math to instead have it map the backdrop
contents back into the CTM local space grossly inflated the size of the
temporary images needed when under many perspective transforms.
This CL instead takes over control of the CTM decomposition and draws
the backdrop (src) content into a temporary layer directly, and then
feeds that through the image filtering. The code is somewhat cumbersome
to follow because of the combination of coordinate spaces and need to
make everything relative to the top left corner of the images.
When the rest of my image filter refactor is more underway, I believe that
a lot of the coordinate space math and image origin accounting will
be much cleaner, but the overall backdrop filtering strategy would remain
similar to this new implementation.

While most callers of decomposeScale only depend on the scale factors
that are returned, image filter decomposition depends on the remaining
matrix as well. Hence, the following necessary updates to work with
the new behavior of decomposeScale:
* Update imagefilter DAG sample to reflect prescaling
* Correct embedded matrix in SkApplyCTMToFilter
* Add comment to clipRectBounds() clarifying coordinate spaces and image filters
But, we want to have decomposeScale using preScale() because it then
produces a remainder matrix that can be used as the transform for the
image filter draw, instead of wrapping the image filter in an
SkMatrixImageFilter as currently done by SkApplyCTMToFilter.

From now on, sample counts always refer to the number of actual color
samples, and render targets don't have separate color and stencil
sample counts.
If mixed samples support is available when making a
"GrAAType::kCoverage" draw, then an op may attach and use a mixed
sampled stencil buffer internally. But this will all be invisible to
the client.
After this CL, we temporarily won't have a mode to use nvpr with mixed
samples. That will soon be fixed by a follow-on CL that enables nvpr
with mixed samples in the normal "gl" and "gles" configs.

Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

This differed from the separate versions in that it snapped to zero.
It was also strictly worse than calling the two separate versions.
Most clients don't need the snapping, so just call the two existing
functions. For clients that need the snapping, call new variants of
each that do snap.

* refactor gradients as Shader subclasses
* introduce ShaderPaint (to support current Gradient-as-paint use)
* introduce ShaderEffect (to support future Gradient-as-effect use)
Tangentially:
* rename SkSGPaintNode.h -> SkSGPaint.h
* consolidate sksg::Color into SkSGPaint.h

Updates the handling of perspective quads to calculate the correct,
degenerate-safe projected quad and then derive from that the proper
perspective quad.
In 2D, updated to determine if the optimized outset/inset procedure
is valid, and if not goes through a more robust procedure that is
based on line equation intersections. In particular, the degenerate
inset/outset approach is used when the quad has a zero-length edge,
if insetting/outsetting normally would create a self-intersecting shape,
or if near parallel edge angles would create numerical instabilities.
Performance testing by forcing all rectangle draws through the degenerate
code path suggests that it is about 10% slower than the optimal approach,
at least on my workstation...

Previously, we relied on ops to deduce whether a draw would have
hardware coverage modulation as a result mixed samples. This is
problematic because *any* draw can have mixed samples coverage if
there is a multisampled stencil clip. No ops were checking for stencil
clip, and most just said they never used mixed samples.
Now that the only usecase for mixed samples is the stencil buffer,
this CL makes the processorSet automatically deduce mixed samples
coverage from the stencil settings and fsaaType.

GrRenderTargetOpList maintains an array of op chains. When it receives a
new op it tries to add it to an existing chain, working backwards from
the end of the current array. If the op can be added to a chain it
additionally tries to merge the new op with ops already in the chain
before adding it to the tail of the chain.
In forward combining it tries to concatenate chains. If chains can
concatenate it also attempts to merge ops between the two chains.
Now op chaining results reported by Op subclasses must be transitive.
Moreover, if op A is able to merge with B then it must be the case that
any op that can chain with A will either merge or chain with any op that
can chain to B.

Implements strokes by linearizing the curve into fine triangle strips
and interpolating a coverage ramp for edge AA. Each triangle in the
strip emits either positive or negative coverage, depending on its
winding direction. Joins and caps are drawn with the existing CCPR
