onscreen/native: Use EGLSyncs instead of cogl_framebuffer_finish 
cogl_framebuffer_finish can result in a CPU-side stall because it waits for
the primary GPU to flush and execute all commands that were queued before
that. By using a GPU-side EGLSync we can let the primary GPU inform us when
it is done with the queued commands instead. We then create another EGLSync
on the secondary GPU using the same fd so the primary GPU effectively
signals the secondary GPU when it is done rendering, causing the latter
to wait for the former before copying part of the frames it needs for
monitors attached to it directly.

This solves the corruption that cogl_framebuffer_finish also solved, but
without needing a CPU-side stall.

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.
