[Mesa-dev] [PATCH v2 3/3] main/get: support ARB_gpu_shader5

[Jordan Justen]

If a driver enables ARB_gpu_shader5 and sets Const.MaxVertexSteams >= 4,
then piglit's arb_gpu_shader5-minmax test should now pass.

v2:
 * MIN_FRAGMENT_INTERPOLATION_OFFSET & MAX_FRAGMENT_INTERPOLATION_OFFSET
   now are NORM_CONST and no longer require fields to be added to
   struct gl_constants
