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.

gdk: Add GdkDisplay::init_gl vfunc The vfunc is called to initialize GL and it returns a "base" context that GDK then uses as the context all others are shared with. So the GL context share tree now looks like: + context from init_gl - context1 - context2 ... So this is a flat tree now, the complexity is gone. The only caveat is that backends now need to create a GL context when initializing GL so some refactoring was needed. Two new functions have been added: * gdk_display_prepare_gl() This is public API and can be used to ensure that GL has been initialized or if not, retrieve an error to display (or debug-print). * gdk_display_get_gl_context() This is a private function to retrieve the base context from init_gl(). It replaces gdk_surface_get_shared_data_context().

macos: implement GL context This implements the basics for a GdkGLContext on macOS. Currently, rendering only is fully working for the GskCairoRenderer case where we read back pixels into a cairo surface for rendering. More work on synchronization is required for the GL on GskGLRenderer case. When we attempt to render a surface itself with GL, the context will ensure that the new GdkMacosGLView is placed within the NSWindow. In other cases, we use a dummy NSView and NSWindow for backing the NSOpenGLContext to ensure that we can get accelerated drawing. This gets GtkGLArea working when running with GSK_RENDERER=cairo.
