This patch adds support for bullet marks on triangle mesh surfaces. I'm not
sure how useful this for vanilla Quake 3 maps as they don't seem to have too
many triangle mesh surfaces.

I originally wrote it for XreaL based engines as they tend to use maps with a
lot more complex triangle mesh surfaces, but it might be useful in vanilla
Quake 3 for custom maps.

Note that the normal-dot-projection-direction check is disabled (same as the
unmodified code) because Quake 3's small triangle meshes tend to have a low
triangle count, and thus sharply changing normals. So it looks better for the
mark to "wrap around" the triangles, rather than having a sharp cut off.

I tested it on the small skull above the hallway near the Yellow Armor on
Q3DM6. Anyway, maybe it's useful for someone... :-)
