LOD terrain breaks

[GoogleCodeExporter]

Any brush which uses LOD terrain (a feature of the FAKK/Übertools branches of 
the Q3 engine, also known apparently as "triangle soups") currently breaks. The 
map can be loaded but these brushes disappear completely in all editors. The 
idea is similar to displacements in the Source engine (creating a complex 
surface without a ridiculous amount of brushes), with a few key differences:
1. Source displacements use vector fields to define surfaces, whereas I believe 
triangle soups specifically define each triangle vertex-by-vertex. As a plus, 
this might be easier to convert to simple brushes for editors that do not 
support it.
2. Since triangles are defined explicitly, there is more flexibility with the 
shapes that can be created. Displacement surfaces must be 4-sided with a 
specific tessellation across the surface, but triangle soups can be any shape 
with each triangle using a specific texture.
3. Given these differences in the systems, their storage in maps (both compiled 
and uncompiled) is very different. Unfortunately, the triangle soup format is 
quite badly documented.

I'll have to do some reverse engineering and other research, and if I'm lucky I 
can figure this out. This might fix the broken terrain in CoD, MoHAA, etc.

I might have to push this one back. There's zero documentation of this 
anywhere, and I'm not reverse engineering it right now.
