Polymer: preliminary support for GL_ARB_debug_output

This won't actually do anything until the a debug bit is added when
creating the context, but that requires support for GLX_create_context
which SDL doesn't support. I'll add support for WGL_create_context to
winlayer in a bit as a stopgap.

Also updates our local copy of glext.h with a fresh one from the
Khronos registry.

Polymer: Fix upside-down projective textures

We need to Y-invert the projection texcoords when sampling
from the lightmap.
