Bugfix #4544

Browse Source 
The 'edge fill' code failed on filling tiny small polygons. It has a limit
check for double points, which was hardcoded set to 0.0003.

That is (commented in code too) a weak part. Better would be to define a
bounding box first, and then derive the limit from that.

Further, the edge fill code uses blender EditEdge data, which fails when
the filling code removes edges. Certainly a topic to work on once, this
code is from the 80ies!
