[Mesa-dev] State of Geometry shader instancing on radeonsi

[Alexandre Demers]

Update on radeonsi's GL_ARB_viewport_array: even though I don't have 
much time right now, the easy part is done. I should push my changes to 
my git tree soon. I'll let you know where it is.

However, I may need some help for the last part, mostly because r600g 
doesn't help a lot on that matter. Then again, I'll let you know if needed.
