According to the OpenGL 2.1 specification, Table 6.11 (Coloring),
GL_FOG_COORD_SRC is supposed to be in the fog attribute.

case GL_HINT_BIT:
DrNick pointed out that I should probably check
ctx->Extensions.EXT_fog_coord before calling this.
Alternatively, it looks like all drivers support EXT_fog_coord (all
Gallium drivers, and classic i915, i965, radeon, r200, nouveau). So
maybe it would be better to change the enable flag to dummy_true and
ignore it here. Thoughts? (And can anyone double check in case I
missed a driver?)
