(MVert,MFace,etc) off into DNA_meshdata_types.h, to isolate areas
of source that actually edit mesh *data* vs. areas that just edit
mesh object information.
different objects shouldn't share flags this way (still sharing of
other mesh flags in renderer... ickity pickity, but I'm not fixing now)
- removed some unnecessary uses of DNA_mesh_types.h
- removed rendermesh_uses_displist (no longer relevant)
- converted appropriate me->flag tests to using mesh_uses_displist
- made vert and face counting (for info header) use proper counts
- changed flip_subdivision to allow level==0 argument
- ps. thanks for subsurf orco fix ton
- reduced main subsurf interface to two functions to make DispListMesh
structures from an editmesh or a regular mesh. for the most part this
means that to implement a geometry modifier you only need to write
these two functions (not very plugable yet however).
- added displistmesh_from_mesh and displistmesh_from_editmesh functions
which allow simple support of subdivLevel(0) subsurfs, somewhat handy
for testing things (like why orco doesn't work for subsurf).
from NaN period, someone just commented out a piece of code... this to
prevent the curve itself being converted (as edges) next to the 3d filled
faces. but for 3D curves there are no filled faces.
