From: Ian Romanick <ian.d.roman...@intel.com>
This is a bit of a hack. _mesa_meta_GenerateMipmap shouldn't even be
used in contexts where GL_GENERATE_MIPMAP doesn't exist (i.e., core
profile and ES2) because it uses fixed-function, and fixed-function
doesn't exist there either!
A GLSL-based _mesa_meta_GenerateMipmap should be available soon.

Without this patch, the in-reply-to patch breaks glGenerateMipmaps in
OpenGL ES 2.0 contexts. With a Reviewed-by, I'll commit this patch
before the other 18 patch series.
