It seems to cut the mesh correctly, but the original mesh seems to remain in 
addition to the new mesh, which covers any holes of the newly cut mesh. 
However, a few of the triangles from the original mesh do get removed.

Basically, if a CSG operation produces two or more submeshes which aren't 
connected, there should be something to detect that. It should be computed 
either automatically or on-demand, so that the user can do stuff with the 
result.

There's already code to divide each of the cut input meshes into regions of 
contiguous faces, stopping at the cuts. Modifying that might be the way to 
go.

This was suggested by Bobboau on the hard-light.net forums.

The external BasicModelData class needs to be replaced with something 
internal, and better designed.

Numerous references to the BasicModelData class will require refactoring.

The project can't be built until this gets fixed.

There's a bunch of redundant code. The code for converting to instances of 
the BasicModelData class is a particularly bad case.

There's also the beginnings of a partial rewrite of a large portion of it 
(just about all of the files with names starting with "CSG" (but not 
CSG.cs)), but that's incomplete.
