shaped-texture: Add support for texture transform This adds the necessary bits to support Wayland buffer transforms. The main part here is to properly setup the Cogl pipeline and to recalculate the size of the painted area accordingly, so culling etc. still works. The choosen approach additionally lays groundwork for Wayland wp_viewporter support. https://gitlab.gnome.org/GNOME/mutter/merge_requests/322

Clean up include macros mess The order and way include macros were structured was chaotic, with no real common thread between files. Try to tidy up the mess with some common scheme, to make things look less messy.

shaped-texture: Implement ClutterContent MetaWindowActor is the compositor-side representative of a MetaWindow. Specifically it represents the geometry of the window under Clutter scene graph. MetaWindowActors are backed by MetaSurfaceActors, that represent the windowing system's surfaces themselves. Naturally, these surfaces have textures with the pixel content of the clients associated with them. These textures are represented by MetaShapedTexture. MetaShapedTextures are currently implemented as ClutterActor subclasses that override the paint function to paint the textures it holds. Conceptually, however, Clutter has an abstraction layer for contents of actors: ClutterContent. Which MetaShapedTexture fits nicely, in fact. Make MetaShapedTexture a ClutterContent implementation. This forces a few changes in the stack: * MetaShapedTexture now handles buffer scale. * We now paint into ClutterPaintNode instead of the direct framebuffer. * Various pieces of Wayland code now use MetaSurfaceActor instead of MetaShapedTexture. * MetaSurfaceActorWayland doesn't override size negotiation vfuncs anymore https://gitlab.gnome.org/GNOME/mutter/merge_requests/409

wayland: Add support for EGL_WAYLAND_Y_INVERTED_WL Add support for inverted Y Wayland buffers. OpenGL textures are by default inverted, so adding support for EGL_WAYLAND_Y_INVERTED_WL effectively means adding support for non-inverted, which makes the MetaShapedTexture apply a transformation when drawing only when querying EGL_WAYLAND_Y_INVERTED_WL resulted in the response "EGL_FALSE". https://bugzilla.gnome.org/show_bug.cgi?id=773629

MetaShapedTexture: Add support for setting a custom CoglSnippet To support special types of buffer types, add support for setting a CoglSnippet on the shaped texture which will then be added to the pipeline. https://bugzilla.gnome.org/show_bug.cgi?id=773629

surface-actor-x11: Make sure to set a size when unredirected When we're unredirected, we don't have a pixmap, and thus our allocation becomes 0x0. So when events come in, they pass right through our actor, going to the one underneath in the stack. Fix this by having a fallback size on the shaped texture actor when we're unredirected, causing it to always have a valid allocation. This fixes clicking on stuff in sloppy / mouse mode focus.

surface-actor-x11: Unredirect ARGB32 windows with full opaque regions We can detect that these windows are already fully opaque, so allow them to unredirect. Allows unredirecting Totem during video playback, giving a significant speed boost.

cairo_region_t * meta_shaped_texture_get_opaque_region (MetaShapedTexture *stex);
shaped-texture: Add API to check opaqueness It is opaque if the texture has no alpha channel, or if the opaque region covers the whole content. Internally uses a function that checks whether there is an alpha channel. This API will be exposed at a later time as well. https://gitlab.gnome.org/GNOME/mutter/merge_requests/734

window-actor: Move shapes, shadows and unredirection to X11 sub types Move out updating of various shapes (input, opaque, shape) indirectly from X11 to the corresponding X11 sub types of MetaWindowActor and MetaSurfaceActor. Also move fullscreen window unredirection code with it. We want to effectively do something similar for MetaCompositorServer, but it will work differently enough not to share too much logic. While it would have been nice to move things piece by piece, things were too intertwined to make it feasible. This has the side effect fixing accidentally and arbitrarily adding server side shadow to Wayland surfaces.
