I've removed editmesh altogether (other then scanfill, which is
seperate code that happens to reuse the editmesh structures).
The compatibility layer I had written for old editmesh tools
was more trouble then it was worth, though it did help in the
early stages of this project.
There's a fair amount of breakage, and there's bunches of tools
(mostly minor ones) I need to port over still. Biggest ones are
join triangles and loop to region, and spin/screw.
This probably isn't really testable, I'll hopefully have more
work done on this soon, but might not be before next week.
(though it's not completely feature-complete yet).
I ported over the remove doubles code from the
old bmesh branch for this, and split it into two
bmops, "Weld Verts" and "Remove Doubles".
Weld verts welds specific verts together, while remove
doubles finds doubles and welds them.
I also reverted the hotkey change I made earlier.
that handles some non-manifold situations better without failing.
Also made edge subdivide use a more specializzed internal version
of BM_Connect_Verts, that should hopefully always split the correct face.
Dissolve verts also now has checks to not accidentally dissolve
unselected vertices. It's not kindof a hybrid tool, using dissolve
faces where it can to dissolve verts for robustness, and using
BM_Dissolve_Verts where it cannot.
And removed some cruft from a few API functions.
that does that needed to be split in two. this made dissolve faces sometimes
not work.
also added some api functions to recalculate normals for verts, edges and
faces. and added a new flag, BM_NONORMCALC, to prevent this from happening
on individual fgon faces after they are tesselated. and made dissolve faces
happen on fkey in all the selection modes, not just face select.
how original edge loop worked, and made it so if it starts
at a boundary edge, it walks across the boundary. I'm not
sure if this is bad, most of the time I do that I want it
to do that anyway.
