[Mesa-dev] [PATCH] i965/gen[45]: Do point coord logic whenever gl_PointCoord is asked for.

[Eric Anholt]

The desktop spec asks for gl_PointCoord to be defined only when
GL_POINT_SPRITE is enabled, and it's undefined otherwise (why?!).  The
ES spec doesn't have GL_POINT_SPRITE and gl_PointCoord is always
defined.  So just make our implementation always give you gl_PointCoord
regardless of the enable.
