Georges Basile Stavracas Neto dd39d7a060 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 manually tracks the content 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

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.

Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
