The new syntax is still in text format, but it uses indices & vertex lists, similar
to how 3DS files work.  I'm not sure of how much space is saved, but it should be
OK.  Being able to read a binary format might also be good, but I don't think that
introducing ANOTHER 3D format would be such a good idea.  Maybe if we could get
POV to read DXF... but then there are copyright issues to deal with.

Patching POV with non-trimmed would involve quite a bit of stuff (but should be
possible if a few people work on it).
