macos: prototype new GDK backend for macOS This is fairly substantial rewrite of the GDK backend for quartz and renamed to macOS to allow for a greenfield implementation. Many things have come across from the quartz implementation fairly intact such as the eventloop integration design and discovery of event windows from the NSEvent. However much has been changed to fit in with the new GDK design and how removal of child GdkWindow have been completely eliminated. Furthermore, the new GdkPopup allows for regular NSWindow to be used to provide popovers unlike the previous implementation. The object design more closely follows the ideal for a GDK backend. Views have been broken out into subclasses so that we can support multiple GSK renderer paths such as GL and Cairo (and Metal in the future). However mixed mode GL and Cairo will not be supported. Currently only the Cairo renderer has been implemented. A new frame clock implementation using CVDisplayLink provides more accurate information about when to draw drawing the next frame. Some testing will need to be done here to understand the power implications of this. This implementation has also gained edge snapping for CSD windows. Some work was also done to ensure that CSD windows have opaque regions registered with the display server. ** This is still very much a work-in-progress ** Some outstanding work that needs to be done: - Finish a GL context for macOS and alternate NSView for GL rendering (possibly using speciailized CALayer for OpenGL). - Input rework to ensure that we don't loose remapping of keys that was dropped from GDK during GTK 4 development. - Make sure input methods continue to work. - Drag-n-Drop is still very much a work in progress - High resolution input scrolling needs various work in GDK to land first before we can plumb that to NSEvent. - gtk/ has a number of things based on GDK_WINDOWING_QUARTZ that need to be updated to use the macOS backend. But this is good enough to start playing with and breaking things which is what I'd like to see.

macos: use CALayer and IOSurface for rendering This provides a major shift in how we draw both when accelerated OpenGL as well as software rendering with Cairo. In short, it uses tiles of Core Animation's CALayer to display contents from an OpenGL or Cairo rendering so that the window can provide partial damage updates. Partial damage is not generally available when using OpenGL as the whole buffer is flipped even if you only submitted a small change using a scissor rect. Thankfully, this speeds up Cairo rendering a bit too by using IOSurface to upload contents to the display server. We use the tiling system we do for OpenGL which reduces overall complexity and differences between them. A New Buffer ============ GdkMacosBuffer is a wrapper around an IOSurfaceRef. The term buffer was used because 1) surface is already used and 2) it loosely maps to a front/back buffer semantic. However, it appears that IOSurfaceRef contents are being retained in some fashion (likely in the compositor result) so we can update the same IOSurfaceRef without flipping as long as we're fast. This appears to be what Chromium does as well, but Firefox uses two IOSurfaceRef and flips between them. We would like to avoid two surfaces because it doubles the GPU VRAM requirements of the application. Changes to Windows ================== Previously, the NSWindow would dynamically change between different types of NSView based on the renderer being used. This is no longer necessary as we just have a single NSView type, GdkMacosView, which inherits from GdkMacosBaseView just to keep the tedius stuff separate from the machinery of GdkMacosView. We can merge those someday if we are okay with that. Changes to Views ================ GdkMacosCairoView, GdkMacosCairoSubView, GdkMacosGLView have all been removed and replaced with GdkMacosView. This new view has a single CALayer (GdkMacosLayer) attached to it which itself has sublayers. The contents of the CALayer is populated with an IOSurfaceRef which we allocated with the GdkMacosSurface. The surface is replaced when the NSWindow resizes. Changes to Layers ================= We now have a dedicated GdkMacosLayer which contains sublayers of GdkMacosTile. The tile has a maximum size of 128x128 pixels in device units. The GdkMacosTile is partitioned by splitting both the transparent region (window bounds minus opaque area) and then by splitting the opaque area. A tile has either translucent contents (and therefore is not opaque) or has opaque contents (and therefore is opaque). An opaque tile never contains transparent contents. As such, the opaque tiles contain a black background so that Core Animation will consider the tile's bounds as opaque. This can be verified with "Quartz Debug -> Show opaque regions". Changes to Cairo ================ GTK 4 cannot currently use cairo-quartz because of how CSS borders are rendered. It simply causes errors in the cairo_quartz_surface_t backend. Since we are restricted to using cairo_image_surface_t (which happens to be faster anyway) we can use the IOSurfaceBaseAddress() to obtain a mapping of the IOSurfaceRef in user-space. It always uses BGRA 32-bit with alpha channel even if we will discard the alpha channel as that is necessary to hit the fast paths in other parts of the platform. Note that while Cairo says CAIRO_FORMAT_ARGB32, it is really 32-bit BGRA on little-endian as we expect. OpenGL will render flipped (Quartz Native Co-ordinates) while Cairo renders with 0,O in the top-left. We could use cairo_translate() and cairo_scale() to reverse this, but it looks like some cairo things may not look quite as right if we do so. To reduce the chances of one-off bugs this continues to draw as Cairo would normally, but instead uses an CGAffineTransform in the tiles and some CGRect translation when swapping buffers to get the same effect. Changes to OpenGL ================= To simplify things, removal of all NSOpenGL* related components have been removed and we strictly use the Core GL (CGL*) API. This probably should have been done long ago anyay. Most examples found in the browsers to use IOSurfaceRef with OpenGL are using Legacy GL and there is still work underway to make this fit in with the rest of how the GSK GL renderer works. Since IOSurfaceRef bound to a texture/framebuffer will not have a default framebuffer ID of 0, we needed to add a default framebuffer id to the GdkGLContext. GskGLRenderer can use this to setup the command queue in such a way that our IOSurface destination has been glBindFramebuffer() as if it were the default drawable. This stuff is pretty slight-of-hand, so where things are and what needs flushing when and where has been a bit of an experiment to see what actually works to get synchronization across subsystems. Efficient Damages ================= After we draw with Cairo, we unlock the IOSurfaceRef and the contents are uploaded to the GPU. To make the contents visible to the app, we must clear the tiles contents with `layer.contents=nil;` and then re-apply the IOSurfaceRef. Since the buffer has likely not changed, we only do this if the tile overlaps the damage region. This gives the effect of having more tightly controlled damage regions even though updating the layer would damage be the whole window (as it is with OpenGL/Metal today with the exception of scissor-rect). This too can be verified usign "Quartz Debug -> Flash screen udpates". Frame Synchronized Resize ========================= In GTK 4, we have the ability to perform sizing changes from compute-size during the layout phase. Since the macOS backend already tracks window resizes manually, we can avoid doing the setFrame: immediately and instead do it within the frame clock's layout phase. Doing so gives us vastly better resize experience as we're more likely to get the size-change and updated-contents in the same frame on screen. It makes things feel "connected" in a way they weren't before. Some additional effort to tweak gravity during the process is also necessary but we were already doing that in the GTK 4 backend. Backporting =========== The design here has made an attempt to make it possible to backport by keeping GdkMacosBuffer, GdkMacosLayer, and GdkMacosTile fairly independent. There may be an opportunity to integrate this into GTK 3's quartz backend with a fair bit of work. Doing so could improve the situation for applications which are damage-rich such as The GIMP.

macos: implement GdkDrop for macOS This gets the basic mechanics of the drop portion of DnD working on the macOS backend. You can drag, for example, from TextEdit into GNOME Text Editor when using the macOS backend. Other content formats are supported, and match what is currently supported by the clipboard backend as the implementation to read from the pasteboard is shared. Currently, we look up the GdkDrag for the new GdkDrop. However, nothing is stashing the drag away for further lookup. More work is needed on GdkMacosDrag for that to be doable.

macos: tweak gravity while resizing This helps a situation where the window contents has not changed in time for a drawing. Setting the texture gravity helps that side or corner to be less jittery while moving. Ideally, we can get to a point where we are synchronized and keeping up with drawing fast enough to not need this. That may require some work to drive frame clocks from drawRect: though.

/* Reset gravity */
macos: use CALayer and IOSurface for rendering This provides a major shift in how we draw both when accelerated OpenGL as well as software rendering with Cairo. In short, it uses tiles of Core Animation's CALayer to display contents from an OpenGL or Cairo rendering so that the window can provide partial damage updates. Partial damage is not generally available when using OpenGL as the whole buffer is flipped even if you only submitted a small change using a scissor rect. Thankfully, this speeds up Cairo rendering a bit too by using IOSurface to upload contents to the display server. We use the tiling system we do for OpenGL which reduces overall complexity and differences between them. A New Buffer ============ GdkMacosBuffer is a wrapper around an IOSurfaceRef. The term buffer was used because 1) surface is already used and 2) it loosely maps to a front/back buffer semantic. However, it appears that IOSurfaceRef contents are being retained in some fashion (likely in the compositor result) so we can update the same IOSurfaceRef without flipping as long as we're fast. This appears to be what Chromium does as well, but Firefox uses two IOSurfaceRef and flips between them. We would like to avoid two surfaces because it doubles the GPU VRAM requirements of the application. Changes to Windows ================== Previously, the NSWindow would dynamically change between different types of NSView based on the renderer being used. This is no longer necessary as we just have a single NSView type, GdkMacosView, which inherits from GdkMacosBaseView just to keep the tedius stuff separate from the machinery of GdkMacosView. We can merge those someday if we are okay with that. Changes to Views ================ GdkMacosCairoView, GdkMacosCairoSubView, GdkMacosGLView have all been removed and replaced with GdkMacosView. This new view has a single CALayer (GdkMacosLayer) attached to it which itself has sublayers. The contents of the CALayer is populated with an IOSurfaceRef which we allocated with the GdkMacosSurface. The surface is replaced when the NSWindow resizes. Changes to Layers ================= We now have a dedicated GdkMacosLayer which contains sublayers of GdkMacosTile. The tile has a maximum size of 128x128 pixels in device units. The GdkMacosTile is partitioned by splitting both the transparent region (window bounds minus opaque area) and then by splitting the opaque area. A tile has either translucent contents (and therefore is not opaque) or has opaque contents (and therefore is opaque). An opaque tile never contains transparent contents. As such, the opaque tiles contain a black background so that Core Animation will consider the tile's bounds as opaque. This can be verified with "Quartz Debug -> Show opaque regions". Changes to Cairo ================ GTK 4 cannot currently use cairo-quartz because of how CSS borders are rendered. It simply causes errors in the cairo_quartz_surface_t backend. Since we are restricted to using cairo_image_surface_t (which happens to be faster anyway) we can use the IOSurfaceBaseAddress() to obtain a mapping of the IOSurfaceRef in user-space. It always uses BGRA 32-bit with alpha channel even if we will discard the alpha channel as that is necessary to hit the fast paths in other parts of the platform. Note that while Cairo says CAIRO_FORMAT_ARGB32, it is really 32-bit BGRA on little-endian as we expect. OpenGL will render flipped (Quartz Native Co-ordinates) while Cairo renders with 0,O in the top-left. We could use cairo_translate() and cairo_scale() to reverse this, but it looks like some cairo things may not look quite as right if we do so. To reduce the chances of one-off bugs this continues to draw as Cairo would normally, but instead uses an CGAffineTransform in the tiles and some CGRect translation when swapping buffers to get the same effect. Changes to OpenGL ================= To simplify things, removal of all NSOpenGL* related components have been removed and we strictly use the Core GL (CGL*) API. This probably should have been done long ago anyay. Most examples found in the browsers to use IOSurfaceRef with OpenGL are using Legacy GL and there is still work underway to make this fit in with the rest of how the GSK GL renderer works. Since IOSurfaceRef bound to a texture/framebuffer will not have a default framebuffer ID of 0, we needed to add a default framebuffer id to the GdkGLContext. GskGLRenderer can use this to setup the command queue in such a way that our IOSurface destination has been glBindFramebuffer() as if it were the default drawable. This stuff is pretty slight-of-hand, so where things are and what needs flushing when and where has been a bit of an experiment to see what actually works to get synchronization across subsystems. Efficient Damages ================= After we draw with Cairo, we unlock the IOSurfaceRef and the contents are uploaded to the GPU. To make the contents visible to the app, we must clear the tiles contents with `layer.contents=nil;` and then re-apply the IOSurfaceRef. Since the buffer has likely not changed, we only do this if the tile overlaps the damage region. This gives the effect of having more tightly controlled damage regions even though updating the layer would damage be the whole window (as it is with OpenGL/Metal today with the exception of scissor-rect). This too can be verified usign "Quartz Debug -> Flash screen udpates". Frame Synchronized Resize ========================= In GTK 4, we have the ability to perform sizing changes from compute-size during the layout phase. Since the macOS backend already tracks window resizes manually, we can avoid doing the setFrame: immediately and instead do it within the frame clock's layout phase. Doing so gives us vastly better resize experience as we're more likely to get the size-change and updated-contents in the same frame on screen. It makes things feel "connected" in a way they weren't before. Some additional effort to tweak gravity during the process is also necessary but we were already doing that in the GTK 4 backend. Backporting =========== The design here has made an attempt to make it possible to backport by keeping GdkMacosBuffer, GdkMacosLayer, and GdkMacosTile fairly independent. There may be an opportunity to integrate this into GTK 3's quartz backend with a fair bit of work. Doing so could improve the situation for applications which are damage-rich such as The GIMP.

macos: fix configure, move-resize, and compute-size This significantly cleans up how we handle various move-resize, compute- size, and configure (notification of changes) in the macOS GDK backend. Originally when prototyping this backend, there were some bits that came over from the quartz backend and some bits which did not. It got confusing and so this makes an attempt to knock down all that technical debt. It is much simpler now in that the GdkMacosSurface makes requests of the GdkMacosWindow, and the GdkMacosWindow notifies the GdkMacosSurface of changes that happen. User resizes are delayed until the next compute-size so that we are much closer to the layout phase, reducing chances for in-between frames. This also improves the situation of leaving maximized state so that a grab and drag feels like you'd expect on other platforms. I removed the opacity hack we had in before, because that is all coming out anyway and it's a bit obnoxious to maintain through the async flows here.

Frame Synchronized Resize ========================= In GTK 4, we have the ability to perform sizing changes from compute-size during the layout phase. Since the macOS backend already tracks window resizes manually, we can avoid doing the setFrame: immediately and instead do it within the frame clock's layout phase. Doing so gives us vastly better resize experience as we're more likely to get the size-change and updated-contents in the same frame on screen. It makes things feel "connected" in a way they weren't before. Some additional effort to tweak gravity during the process is also necessary but we were already doing that in the GTK 4 backend. Backporting =========== The design here has made an attempt to make it possible to backport by keeping GdkMacosBuffer, GdkMacosLayer, and GdkMacosTile fairly independent. There may be an opportunity to integrate this into GTK 3's quartz backend with a fair bit of work. Doing so could improve the situation for applications which are damage-rich such as The GIMP.

macos: prototype new GDK backend for macOS This is fairly substantial rewrite of the GDK backend for quartz and renamed to macOS to allow for a greenfield implementation. Many things have come across from the quartz implementation fairly intact such as the eventloop integration design and discovery of event windows from the NSEvent. However much has been changed to fit in with the new GDK design and how removal of child GdkWindow have been completely eliminated. Furthermore, the new GdkPopup allows for regular NSWindow to be used to provide popovers unlike the previous implementation. The object design more closely follows the ideal for a GDK backend. Views have been broken out into subclasses so that we can support multiple GSK renderer paths such as GL and Cairo (and Metal in the future). However mixed mode GL and Cairo will not be supported. Currently only the Cairo renderer has been implemented. A new frame clock implementation using CVDisplayLink provides more accurate information about when to draw drawing the next frame. Some testing will need to be done here to understand the power implications of this. This implementation has also gained edge snapping for CSD windows. Some work was also done to ensure that CSD windows have opaque regions registered with the display server. ** This is still very much a work-in-progress ** Some outstanding work that needs to be done: - Finish a GL context for macOS and alternate NSView for GL rendering (possibly using speciailized CALayer for OpenGL). - Input rework to ensure that we don't loose remapping of keys that was dropped from GDK during GTK 4 development. - Make sure input methods continue to work. - Drag-n-Drop is still very much a work in progress - High resolution input scrolling needs various work in GDK to land first before we can plumb that to NSEvent. - gtk/ has a number of things based on GDK_WINDOWING_QUARTZ that need to be updated to use the macOS backend. But this is good enough to start playing with and breaking things which is what I'd like to see.

macos: use CALayer and IOSurface for rendering This provides a major shift in how we draw both when accelerated OpenGL as well as software rendering with Cairo. In short, it uses tiles of Core Animation's CALayer to display contents from an OpenGL or Cairo rendering so that the window can provide partial damage updates. Partial damage is not generally available when using OpenGL as the whole buffer is flipped even if you only submitted a small change using a scissor rect. Thankfully, this speeds up Cairo rendering a bit too by using IOSurface to upload contents to the display server. We use the tiling system we do for OpenGL which reduces overall complexity and differences between them. A New Buffer ============ GdkMacosBuffer is a wrapper around an IOSurfaceRef. The term buffer was used because 1) surface is already used and 2) it loosely maps to a front/back buffer semantic. However, it appears that IOSurfaceRef contents are being retained in some fashion (likely in the compositor result) so we can update the same IOSurfaceRef without flipping as long as we're fast. This appears to be what Chromium does as well, but Firefox uses two IOSurfaceRef and flips between them. We would like to avoid two surfaces because it doubles the GPU VRAM requirements of the application. Changes to Windows ================== Previously, the NSWindow would dynamically change between different types of NSView based on the renderer being used. This is no longer necessary as we just have a single NSView type, GdkMacosView, which inherits from GdkMacosBaseView just to keep the tedius stuff separate from the machinery of GdkMacosView. We can merge those someday if we are okay with that. Changes to Views ================ GdkMacosCairoView, GdkMacosCairoSubView, GdkMacosGLView have all been removed and replaced with GdkMacosView. This new view has a single CALayer (GdkMacosLayer) attached to it which itself has sublayers. The contents of the CALayer is populated with an IOSurfaceRef which we allocated with the GdkMacosSurface. The surface is replaced when the NSWindow resizes. Changes to Layers ================= We now have a dedicated GdkMacosLayer which contains sublayers of GdkMacosTile. The tile has a maximum size of 128x128 pixels in device units. The GdkMacosTile is partitioned by splitting both the transparent region (window bounds minus opaque area) and then by splitting the opaque area. A tile has either translucent contents (and therefore is not opaque) or has opaque contents (and therefore is opaque). An opaque tile never contains transparent contents. As such, the opaque tiles contain a black background so that Core Animation will consider the tile's bounds as opaque. This can be verified with "Quartz Debug -> Show opaque regions". Changes to Cairo ================ GTK 4 cannot currently use cairo-quartz because of how CSS borders are rendered. It simply causes errors in the cairo_quartz_surface_t backend. Since we are restricted to using cairo_image_surface_t (which happens to be faster anyway) we can use the IOSurfaceBaseAddress() to obtain a mapping of the IOSurfaceRef in user-space. It always uses BGRA 32-bit with alpha channel even if we will discard the alpha channel as that is necessary to hit the fast paths in other parts of the platform. Note that while Cairo says CAIRO_FORMAT_ARGB32, it is really 32-bit BGRA on little-endian as we expect. OpenGL will render flipped (Quartz Native Co-ordinates) while Cairo renders with 0,O in the top-left. We could use cairo_translate() and cairo_scale() to reverse this, but it looks like some cairo things may not look quite as right if we do so. To reduce the chances of one-off bugs this continues to draw as Cairo would normally, but instead uses an CGAffineTransform in the tiles and some CGRect translation when swapping buffers to get the same effect. Changes to OpenGL ================= To simplify things, removal of all NSOpenGL* related components have been removed and we strictly use the Core GL (CGL*) API. This probably should have been done long ago anyay. Most examples found in the browsers to use IOSurfaceRef with OpenGL are using Legacy GL and there is still work underway to make this fit in with the rest of how the GSK GL renderer works. Since IOSurfaceRef bound to a texture/framebuffer will not have a default framebuffer ID of 0, we needed to add a default framebuffer id to the GdkGLContext. GskGLRenderer can use this to setup the command queue in such a way that our IOSurface destination has been glBindFramebuffer() as if it were the default drawable. This stuff is pretty slight-of-hand, so where things are and what needs flushing when and where has been a bit of an experiment to see what actually works to get synchronization across subsystems. Efficient Damages ================= After we draw with Cairo, we unlock the IOSurfaceRef and the contents are uploaded to the GPU. To make the contents visible to the app, we must clear the tiles contents with `layer.contents=nil;` and then re-apply the IOSurfaceRef. Since the buffer has likely not changed, we only do this if the tile overlaps the damage region. This gives the effect of having more tightly controlled damage regions even though updating the layer would damage be the whole window (as it is with OpenGL/Metal today with the exception of scissor-rect). This too can be verified usign "Quartz Debug -> Flash screen udpates".

macos: prototype new GDK backend for macOS This is fairly substantial rewrite of the GDK backend for quartz and renamed to macOS to allow for a greenfield implementation. Many things have come across from the quartz implementation fairly intact such as the eventloop integration design and discovery of event windows from the NSEvent. However much has been changed to fit in with the new GDK design and how removal of child GdkWindow have been completely eliminated. Furthermore, the new GdkPopup allows for regular NSWindow to be used to provide popovers unlike the previous implementation. The object design more closely follows the ideal for a GDK backend. Views have been broken out into subclasses so that we can support multiple GSK renderer paths such as GL and Cairo (and Metal in the future). However mixed mode GL and Cairo will not be supported. Currently only the Cairo renderer has been implemented. A new frame clock implementation using CVDisplayLink provides more accurate information about when to draw drawing the next frame. Some testing will need to be done here to understand the power implications of this. This implementation has also gained edge snapping for CSD windows. Some work was also done to ensure that CSD windows have opaque regions registered with the display server. ** This is still very much a work-in-progress ** Some outstanding work that needs to be done: - Finish a GL context for macOS and alternate NSView for GL rendering (possibly using speciailized CALayer for OpenGL). - Input rework to ensure that we don't loose remapping of keys that was dropped from GDK during GTK 4 development. - Make sure input methods continue to work. - Drag-n-Drop is still very much a work in progress - High resolution input scrolling needs various work in GDK to land first before we can plumb that to NSEvent. - gtk/ has a number of things based on GDK_WINDOWING_QUARTZ that need to be updated to use the macOS backend. But this is good enough to start playing with and breaking things which is what I'd like to see.

macos: fix configure, move-resize, and compute-size This significantly cleans up how we handle various move-resize, compute- size, and configure (notification of changes) in the macOS GDK backend. Originally when prototyping this backend, there were some bits that came over from the quartz backend and some bits which did not. It got confusing and so this makes an attempt to knock down all that technical debt. It is much simpler now in that the GdkMacosSurface makes requests of the GdkMacosWindow, and the GdkMacosWindow notifies the GdkMacosSurface of changes that happen. User resizes are delayed until the next compute-size so that we are much closer to the layout phase, reducing chances for in-between frames. This also improves the situation of leaving maximized state so that a grab and drag feels like you'd expect on other platforms. I removed the opacity hack we had in before, because that is all coming out anyway and it's a bit obnoxious to maintain through the async flows here.

Ideally, we can get to a point where we are synchronized and keeping up with drawing fast enough to not need this. That may require some work to drive frame clocks from drawRect: though.

macos: fix configure, move-resize, and compute-size This significantly cleans up how we handle various move-resize, compute- size, and configure (notification of changes) in the macOS GDK backend. Originally when prototyping this backend, there were some bits that came over from the quartz backend and some bits which did not. It got confusing and so this makes an attempt to knock down all that technical debt. It is much simpler now in that the GdkMacosSurface makes requests of the GdkMacosWindow, and the GdkMacosWindow notifies the GdkMacosSurface of changes that happen. User resizes are delayed until the next compute-size so that we are much closer to the layout phase, reducing chances for in-between frames. This also improves the situation of leaving maximized state so that a grab and drag feels like you'd expect on other platforms. I removed the opacity hack we had in before, because that is all coming out anyway and it's a bit obnoxious to maintain through the async flows here.

macos: prototype new GDK backend for macOS This is fairly substantial rewrite of the GDK backend for quartz and renamed to macOS to allow for a greenfield implementation. Many things have come across from the quartz implementation fairly intact such as the eventloop integration design and discovery of event windows from the NSEvent. However much has been changed to fit in with the new GDK design and how removal of child GdkWindow have been completely eliminated. Furthermore, the new GdkPopup allows for regular NSWindow to be used to provide popovers unlike the previous implementation. The object design more closely follows the ideal for a GDK backend. Views have been broken out into subclasses so that we can support multiple GSK renderer paths such as GL and Cairo (and Metal in the future). However mixed mode GL and Cairo will not be supported. Currently only the Cairo renderer has been implemented. A new frame clock implementation using CVDisplayLink provides more accurate information about when to draw drawing the next frame. Some testing will need to be done here to understand the power implications of this. This implementation has also gained edge snapping for CSD windows. Some work was also done to ensure that CSD windows have opaque regions registered with the display server. ** This is still very much a work-in-progress ** Some outstanding work that needs to be done: - Finish a GL context for macOS and alternate NSView for GL rendering (possibly using speciailized CALayer for OpenGL). - Input rework to ensure that we don't loose remapping of keys that was dropped from GDK during GTK 4 development. - Make sure input methods continue to work. - Drag-n-Drop is still very much a work in progress - High resolution input scrolling needs various work in GDK to land first before we can plumb that to NSEvent. - gtk/ has a number of things based on GDK_WINDOWING_QUARTZ that need to be updated to use the macOS backend.

macos: prototype new GDK backend for macOS This is fairly substantial rewrite of the GDK backend for quartz and renamed to macOS to allow for a greenfield implementation. Many things have come across from the quartz implementation fairly intact such as the eventloop integration design and discovery of event windows from the NSEvent. However much has been changed to fit in with the new GDK design and how removal of child GdkWindow have been completely eliminated. Furthermore, the new GdkPopup allows for regular NSWindow to be used to provide popovers unlike the previous implementation. The object design more closely follows the ideal for a GDK backend. Views have been broken out into subclasses so that we can support multiple GSK renderer paths such as GL and Cairo (and Metal in the future). However mixed mode GL and Cairo will not be supported. Currently only the Cairo renderer has been implemented. A new frame clock implementation using CVDisplayLink provides more accurate information about when to draw drawing the next frame. Some testing will need to be done here to understand the power implications of this. This implementation has also gained edge snapping for CSD windows. Some work was also done to ensure that CSD windows have opaque regions registered with the display server. ** This is still very much a work-in-progress ** Some outstanding work that needs to be done: - Finish a GL context for macOS and alternate NSView for GL rendering (possibly using speciailized CALayer for OpenGL). - Input rework to ensure that we don't loose remapping of keys that was dropped from GDK during GTK 4 development. - Make sure input methods continue to work. - Drag-n-Drop is still very much a work in progress - High resolution input scrolling needs various work in GDK to land first before we can plumb that to NSEvent. - gtk/ has a number of things based on GDK_WINDOWING_QUARTZ that need to be updated to use the macOS backend. But this is good enough to start playing with and breaking things which is what I'd like to see.

We were already handlign the state transitions from the setStyleMask: halper, but we didn't previously tell the window we are allowed to transition into that.

macos: use CALayer and IOSurface for rendering This provides a major shift in how we draw both when accelerated OpenGL as well as software rendering with Cairo. In short, it uses tiles of Core Animation's CALayer to display contents from an OpenGL or Cairo rendering so that the window can provide partial damage updates. Partial damage is not generally available when using OpenGL as the whole buffer is flipped even if you only submitted a small change using a scissor rect. Thankfully, this speeds up Cairo rendering a bit too by using IOSurface to upload contents to the display server. We use the tiling system we do for OpenGL which reduces overall complexity and differences between them. A New Buffer ============ GdkMacosBuffer is a wrapper around an IOSurfaceRef. The term buffer was used because 1) surface is already used and 2) it loosely maps to a front/back buffer semantic. However, it appears that IOSurfaceRef contents are being retained in some fashion (likely in the compositor result) so we can update the same IOSurfaceRef without flipping as long as we're fast. This appears to be what Chromium does as well, but Firefox uses two IOSurfaceRef and flips between them. We would like to avoid two surfaces because it doubles the GPU VRAM requirements of the application. Changes to Windows ================== Previously, the NSWindow would dynamically change between different types of NSView based on the renderer being used. This is no longer necessary as we just have a single NSView type, GdkMacosView, which inherits from GdkMacosBaseView just to keep the tedius stuff separate from the machinery of GdkMacosView. We can merge those someday if we are okay with that. Changes to Views ================ GdkMacosCairoView, GdkMacosCairoSubView, GdkMacosGLView have all been removed and replaced with GdkMacosView. This new view has a single CALayer (GdkMacosLayer) attached to it which itself has sublayers. The contents of the CALayer is populated with an IOSurfaceRef which we allocated with the GdkMacosSurface. The surface is replaced when the NSWindow resizes. Changes to Layers ================= We now have a dedicated GdkMacosLayer which contains sublayers of GdkMacosTile. The tile has a maximum size of 128x128 pixels in device units. The GdkMacosTile is partitioned by splitting both the transparent region (window bounds minus opaque area) and then by splitting the opaque area. A tile has either translucent contents (and therefore is not opaque) or has opaque contents (and therefore is opaque). An opaque tile never contains transparent contents. As such, the opaque tiles contain a black background so that Core Animation will consider the tile's bounds as opaque. This can be verified with "Quartz Debug -> Show opaque regions". Changes to Cairo ================ GTK 4 cannot currently use cairo-quartz because of how CSS borders are rendered. It simply causes errors in the cairo_quartz_surface_t backend. Since we are restricted to using cairo_image_surface_t (which happens to be faster anyway) we can use the IOSurfaceBaseAddress() to obtain a mapping of the IOSurfaceRef in user-space. It always uses BGRA 32-bit with alpha channel even if we will discard the alpha channel as that is necessary to hit the fast paths in other parts of the platform. Note that while Cairo says CAIRO_FORMAT_ARGB32, it is really 32-bit BGRA on little-endian as we expect. OpenGL will render flipped (Quartz Native Co-ordinates) while Cairo renders with 0,O in the top-left. We could use cairo_translate() and cairo_scale() to reverse this, but it looks like some cairo things may not look quite as right if we do so. To reduce the chances of one-off bugs this continues to draw as Cairo would normally, but instead uses an CGAffineTransform in the tiles and some CGRect translation when swapping buffers to get the same effect. Changes to OpenGL ================= To simplify things, removal of all NSOpenGL* related components have been removed and we strictly use the Core GL (CGL*) API. This probably should have been done long ago anyay. Most examples found in the browsers to use IOSurfaceRef with OpenGL are using Legacy GL and there is still work underway to make this fit in with the rest of how the GSK GL renderer works. Since IOSurfaceRef bound to a texture/framebuffer will not have a default framebuffer ID of 0, we needed to add a default framebuffer id to the GdkGLContext. GskGLRenderer can use this to setup the command queue in such a way that our IOSurface destination has been glBindFramebuffer() as if it were the default drawable. This stuff is pretty slight-of-hand, so where things are and what needs flushing when and where has been a bit of an experiment to see what actually works to get synchronization across subsystems. Efficient Damages ================= After we draw with Cairo, we unlock the IOSurfaceRef and the contents are uploaded to the GPU. To make the contents visible to the app, we must clear the tiles contents with `layer.contents=nil;` and then re-apply the IOSurfaceRef. Since the buffer has likely not changed, we only do this if the tile overlaps the damage region. This gives the effect of having more tightly controlled damage regions even though updating the layer would damage be the whole window (as it is with OpenGL/Metal today with the exception of scissor-rect). This too can be verified usign "Quartz Debug -> Flash screen udpates". Frame Synchronized Resize ========================= In GTK 4, we have the ability to perform sizing changes from compute-size during the layout phase. Since the macOS backend already tracks window resizes manually, we can avoid doing the setFrame: immediately and instead do it within the frame clock's layout phase. Doing so gives us vastly better resize experience as we're more likely to get the size-change and updated-contents in the same frame on screen. It makes things feel "connected" in a way they weren't before. Some additional effort to tweak gravity during the process is also necessary but we were already doing that in the GTK 4 backend. Backporting =========== The design here has made an attempt to make it possible to backport by keeping GdkMacosBuffer, GdkMacosLayer, and GdkMacosTile fairly independent. There may be an opportunity to integrate this into GTK 3's quartz backend with a fair bit of work. Doing so could improve the situation for applications which are damage-rich such as The GIMP.
