The patch was by Wael El Oraiby, who did a great job on it.
Yay for Wael! Commit of patch #19242.
There's also some CCGSubSurf stuff mixed in with this, though it's
still not working right (fixed tons of bugs, just the main ones
for some reason are still there, despite their original causes
being fixed :-/).
as does only edges and individual faces extrude (individual vert
extrude already did).
Note that I need to port this, after we all figure out how to handle
operators with variable transform follow-ons.
I also implemented the merge->collapse function, which is currently
accessable under ctrl->v, Bmesh Test Operator. I still need to
implement the other merge modes, and properly hook everything into
the merge menu tool, which I plan on doing soon (tomorrow hopefully).
The cool thing about the collapse tool, is not only does it handle (all)
UV layers, it handles vcols as well. To do this, I had to add a few math
functions to the customdata API, which seem to be working well.
(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.
bmop, that just multiplies input verts with a matrix. Also
made a derivative translate bmop.
BMO_CallOpf now has a %s format code, which is used to
copy data from another slot.
Also cleaned the extrude code up some more, and restored extrude-repeat
(which is bound to ctrl-alt-4), though this doesn't work right yet
(the view matrix it uses is incorrect, or something like that).
