I tried the new code at school (WindowsNT 4, MSVC 6 debugger), and all
examples that use polygon3d[_f] give corrupt *heap* on exit (actually,
VC reports this on exit, so it may happen sooner). Other examples work
fine. In ex3d, the wireframe works fine; I don't get any problems on
exit. But if I use any other modes, then I (radomly) get heap
corruption. I'll look into this this week.
