MetaShapedTexture: Make public and directly derive from ClutterActor ClutterTexture has many features that we simply don't use and don't make sense for a subclass with custom drawing. Deriving directly from ClutterActor simplifies our code by avoiding workarounds and makes things more robust. Additionally, make it public. GNOME Shell was already assuming that any MetaShapedTexture was also a ClutterTexture, and we need to replace these bits with new API for GNOME Shell to use. https://bugzilla.gnome.org/show_bug.cgi?id=660941

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.

meta-shaped-texture: Don't queue redraws for obscured regions When we get a damage event we update the window by calling meta_shaped_texture_update_area which queues a redraw on the actor. We can avoid that for obscured regions by comparing the damage area to our visible area. This patch causes _NET_WM_FRAME_DRAWN messages to be not sent in some cases where they should be sent; they will be added back in a later commit. https://bugzilla.gnome.org/show_bug.cgi?id=703332

shaped-texture: Turn blending off when drawing entirely opaque regions When drawing entirely opaque regions, we traditionally kept blending on simply because it made the code more convenient and obvious to handle. However, this can cause lots of performance issues on GPUs that aren't too powerful, as they have to readback the buffer underneath. Keep track of the opaque region set by windows (through _NET_WM_OPAQUE_REGION, Wayland opaque_region hints, standard RGB32 frame masks or similar), and draw those rectangles separately through a different path with blending turned off. https://bugzilla.gnome.org/show_bug.cgi?id=707019
