[Mesa-dev] [PATCH] i965: Make fs gl_PrimitiveID input work even when there's no gs.

When a geometry shader is present, the fragment shader gl_PrimitiveID input acts like an ordinary varying, receiving data from the gs gl_PrimitiveID output. When there's no geometry shader, we have to ask the fixed function SF hardware to provide the primitive ID to the fragment shader instead. P
