- Removed the gen_utils.c dependency from Mathutils (since gen_utils wont go into 2.5 but mathutils will), repalced with python functions.
- removed Blender.Mathutils.Point, since it was not documented, the C api never used it, none of our scripts used it (and I never saw a script that used it).
I was careful in selectively rolling back revisions, but if you've committed changes unrelated to BPY mixed with BPY changes, I might have reverted those too, so please double check.
packing 2400 rectanges is about 38x faster.
Use the C implimentation in uvcalc_lightmap and uvcalc_smart_project
Blender.c - filename returning None raises errors with existing scripts, just return "" so string functions on the filename dont raise an error.
