[Mesa-dev] [PATCH] main: GL_RGB10_A2UI does not come with GL 3.0/EXT_texture_integer

[Ilia Mirkin]

Add a separate extension check for that format. Prevents glTexImage from
trying to find a matching format, which fails on drivers without support
for this format.

Fixes: sized-texture-format-channels (on a3xx)

Technically we should be exposing it on a3xx, as it's required by ES 3.0.
However I've thus far failed to do so in a way that actually works for all
the necessary use-cases.
