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

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.

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

Implement particles as points.
...
Unfortunately, the maximum point size on Intel hardwar seems to be 1, so I
can't tell if the colors are right.
This is largely just a hacked version of GL's particle code.

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.
