(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.
to bmesh. Yay! Creating faces from edge nets
is sill missing, I'm leaving that for later.
I added two new bmop functions, BMO_HeaderFlag_Buffer
and BMO_UnHeaderFlag_Buffer, which are header flag
version of BMO_Flag_Buffer and BMO_Unflag_Buffer.
The new functions properly handle setting/clearing
BM_SELECT via the selection API.
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).
BMO_ITER macros to make defining iterator
loops easier. Moved some files around.
And also made the editmesh conversion functions
tesselate ngons to triangle fans, since it's
more stable for conversion, and editmeshes are
never displayed to the user anyway. And ported
akey to bmesh.
Next up I plan on adding face iterators to DerivedMesh,
since that's the last major chunk of major refactoring
left, I think, except perhaps the uv editor (at the
moment it's probably close to working, but it's still
converting to editmeshes for everything, which is very
bad).
