The triangulation method I've seen involves connecting the start point in the polygon to all of the others which aren't already attached to the start point.  So one loop covers quads and n-gons.  It would seem that we'd get a lot of the "skinny" polys that way, but you're right - it doesn't seem like that would impact us much, if at all.

I think a list to correlate pverts to the broken down polys would be the place to start.  Break them down, create new indices, keep track of how the new and old indices match up.  Then use the list of new indices when listing regions and edges.

Hmm.  Probably more complicated than I think, as usual.  :-P
