Sebastian Wick 1a09f44c60 cogl/gles: Revert to unsized GL_BGRA as internalformat for BGRA_8888 
Using GL_BGRA8_EXT as internalformat for TexSubImage2D was not allowed
in the EXT_texture_format_BGRA8888 extension. This changed recently:

https://registry.khronos.org/OpenGL/extensions/EXT/EXT_texture_format_BGRA8888.txt

  1.4, 23/06/2024 Erik Faye-Lund: Add GL_BGRA8_EXT for ES 2.0 and later.

Mesa already supports this which is why 7f943613a8 ("cogl: Use sized
internal renderable formats") worked as intended. Technically spec
compliant and our CI had an up-to-date driver.

So while this is no bug, it's still not great because older drivers will
generate GL errors. This commit changes this specific format back to an
unsized internal format which means we could, in theory, get less than
8bpc framebuffers.

We can try to revert this commit when newer driver versions have
propagated far enough.

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.
