implementations (slightly redundant, could implement draw in terms
of first... can be cleaned later)
- switch to use of new APIs... all uses of EditVert->ssco are now
clean (read: ready to die as soon as a proper DerivedMesh implementation
is swapped in with ccgsubsurf)
implementations
- updated drawobject selection code to use DerivedMesh (last DispListMesh
usage in drawobject.c that needs to be replaced! Woot!)
- interface could still be a lot cleaner, mostly calculating indices for
the various things to pass to selection color routine is hacky.
this is to ease migration.
- updated particles and STL converter to use DerivedMesh interface. This
is a bit wasteful at the moment, but these are not key performance areas.
Can update once DerivedMesh has accessors for faces and face data.
