4d7ffc85f9 Make coplanar faces work properly, by implementing a 2d BSP on each 
set of coplanar faces. The polygon count still gets stupid fast;
I'm thinking I can fix that by adding some extra test planes at the
top of the 3d BSP, to quickly cull out stuff that doesn't intersect
us.

de46118324 Add code to extrude a triangle mesh, and to perform Boolean ops on 
a triangle mesh in a BSP. That works, although it splits too often,
the initial triangulations are not good quality, and coplanar faces
are not yet handled. I'll do the coplanar thing tomorrow.
