[Piglit] [PATCH 0/4] Test gl_PrimitiveID in instanced draws

[Nicolai Hähnle]

Hi all,

these tests add coverage for checking that gl_PrimitiveID resets at the
start of a new instance. Radeon GPUs require a few subtleties in
hardware to make sure that works correctly, and we were missing some
of them. Please review!

Thanks,
Nicolai
