the runtime is spent in that function. I should probably write a faster
vertex finding routine, since I currently just do a linear search through
all the vertices. That ought to help speed up SplitSegs, the second most
time-consuming routine. I also tried storing vertices as doubles instead
of fixeds, but that made performance drop across the board, so that's a
change that didn't make it in.
Ironically, the GCC compiled version is noticeably faster than the VC
version for x87 math, but VC produces a marginally faster SSE2 version.
