Subject: main: GL_RGB10_A2UI does not come with GL 3.0/EXT_texture_integer
X-Git-Tag: upstream/17.1.0~6597
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=36347c8d6f265fb9b8ebcd598b189d3b43d6b513;p=platform%2Fupstream%2Fmesa.git

main: GL_RGB10_A2UI does not come with GL 3.0/EXT_texture_integer

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)
