Robert Mader bd6196f4ca wayland: Implement direct scanout for cropped and scaled surfaces 
Until now we only supported direct scanout to the primary plane if the
buffer size perfectly matched the display size.
Since display controllers usually support scaling and cropping buffers
highly efficiently, try to let them do the job. This is usually helpful
if wp_viewporter is used by the client or Mutter uses fractional
scaling.

This has several advantages:
 - Games (e.g. SDL2 based ones) can almost always hit direct scanout
   paths in fullscreen mode. Notably when fractional scaling is used or
   the game renders in a non-native resolution (or both).
 - Video players using YUV buffer formats and wp_viewporter can easily
   hit direct scanout paths, making displaying video very power
   efficient as the 3D engine is not used at all.

Note that this still only uses the primary plane, no overlay or underlay
planes, making this change comparatively low risk.

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 of 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.
