In the previous commits, we added the possibility to use pixel formats which are complex (YUV-based and/or multi-planar) inside Cogl. Use this new feature by assuming we get a CoglMultiPlaneTexture, rather than a "simple" CoglTexture. To easily test whether this works, one can use GStreamer pipelines (you'll need gst-plugins-bad for this to work): For normal BGRA (this should already work before this commit): ``` $ gst-launch-1.0 videotestsrc ! "video/x-raw" ! waylandsink ``` For NV12 (a popular video format): ``` $ gst-launch-1.0 videotestsrc ! "video/x-raw,format=NV12" ! waylandsink ``` For YUV 4:2:2 (another video format): ``` $ gst-launch-1.0 videotestsrc ! "video/x-raw,format=Y42B" ! waylandsink ``` You can also replace with other video sinks, like `vaapisink`. `glimagesink` also works, but for some reason seems to unconditionally convert to RGBA before submitting a texture (so it doesn't do a lot really).

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.

The coding style used is primarily the GNU flavor of the GNOME coding
style
with some minor additions such as preferring stdint.h types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
