Subject: [PATCH 1/2] gl-renderer: Take a list of acceptable formats in create
functions
Currently we pass either a single format or no formats to the gl renderer
create and output_create functions. We extend this to any number of
formats so we can allow fallback formats if we don't get our first pick.

From c4cfe85d3af007e9fa30f10d10fa502ca1336fa6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] compositor-drm: pass ARGB fallback to gl create functions
for XRGB formats
If the GL implementation doesn't provide an XRGB visual we may still be
able to proceed with an ARGB one. Since we're not changing the scanout
buffer format, and our current rendering loop always results in saturated
alpha in the frame buffer, it should be Just Fine(tm) - and probably better
than just exiting.
This is a workaround for https://bugs.freedesktop.org/show_bug.cgi?id=89689
