Description Mark Janes 2016-12-30 08:06:22 UTC 
Four related tests regressed on g33 at:

f3739810e337d0f03514b9b967594c8dc010dfa4
mesa/texformat: Handle GL_RGBA + GL_UNSIGNED_SHORT_5_5_5_1

_mesa_choose_tex_format() already handles GL_RGBA + GL_UNSIGNED_SHORT_1_5_5_5_REV
by converting it to MESA_FORMAT_B5G5R5A1_UNORM. Teach it do the same for
the non-reversed type. Otherwise, the switch's fallthrough converts it
to an 8888 format, which has incompatible precision in the alpha
channel.

Patch 2/2 to fix dEQP-EGL.functional.image.modify.tex_rgb5_a1_tex_subimage_rgba8
on Intel.
