[Mesa-dev] Mesa (master): r300g: fix gl_PointCoord

[Luca Barbieri]

OpenGL 4.1 compatibility profile says:
<<
All fragments produced in rasterizing a point sprite are assigned the same as-
sociated data, which are those of the vertex corresponding to the
point. However,
the fragment shader built-in gl_PointCoord contains point sprite texture coor-
dinates. Additionally, for each texture coordinate set where COORD_REPLACE is
TRUE, these texture coordinates are replaced with point sprite texture
coordinates.

I think "texture coordinates" here must refer to gl_TexCoord[i].
