Settable (in preferences) max verts per polygon
Making Polys won't let you go over the max verts. Some QA for boxer -> engine

Displays message box after removal of dupe verts that it removed it so people are aware of why 2 verts just deleted themselves.
forgot to turn imageframe path writing back on.
