From: Gregory Hainaut <gregory.hain...@gmail.com>
This was originally included in another patch, but it was split out by
Ian Romanick.
v2 (idr):
* Trivial reformatting.
* Remove GL_COMPUTE_SHADER. Compute shaders don't participate in pipeline
objects anyway. Suggested by Matt Turner.
v3 (idr):
* Use _mesa_has_geometry_shaders.
