[Mesa-dev] [PATCH 1/2] egl/wayland: Add 10bpc BGR configs

[Mario Kleiner]

Tested with a hacked weston (to add xbgr2101010 support) under x11 and
drm backend (with wl_drm and wl_dmabuf). All colors are displaying
correctly, and "glmark2-wayland -d" confirms use of a RGBA 10-10-10-2
config. Also works with DRI_PRIME=1 for renderoffload to a AMD gpu.

It did need some more patches to work though. I'll send out a series
on top of your patches shortly to complete this.
