7d8b0f96d6 Correct the fog distance calculations.
It turns out the pixel's z coord is correctly obtailed by
gl_FragCoord.z/gl_FragCoord.w.

c4309e7abc Correct the fog blend calculation for transparency.
The incoming pixel's alpha should not be affected by fog. This fixes the
ugly square smoke particles in foggy maps.

37260018a2 Acutally use the vertex colors for alias models.
Thanks to Spirit trying QF on nvidia drivers, the missing attributes were
found. Now he shouldn't get gl errors :)

731236ee07 Implement global fog.
Sprites and particles don't seem to be getting fogged correctly, but bsp
and alias models are working.

c884ef5f80 Convert the colormap to a 2D palette.
This skips one level of indirection in the alias model and brush shaders.
Hopefully, this will improve performance on my eeepc.

928dd92276 Use 0.0 instead of 0.5 for t for palette lookups.
I realized it's pretty silly using colormap + palette when I can just
combine the two into one and have a 2D palette. This is in preparation for
that.

209c4cda8b Scale the light level index correctly before colormap lookup.
With this, lighting seems to be working. I'm not certain the normals are
100% correct, but I can see something happening on rotating models.

d1419c30db Make a start on alias model rendering.
The vertex and fragment shaders are written, and R_InitAlias is stubbed,
but that's it so far.
