- new feature, twiddled with lattice resizing to try to maintain existing vertex changes... much nicer than just resetting the lattice if you decide you need more detail in the lattice. - modifiers work with lattices now. yes, that does mean you can make a chain of lattices effecting each other 8 miles long. - some cleanup of softbody code, was rather splintered and call path was twisted and confusing. reworked main object step routine to do things in a more obvious and consistent manner and without duplicate code - added ob->softflag OB_SB_RESET instead of sbObjectReset call - modifier changes reset softbody now - moved curve_getVertexCos/curve_applyVertexCos into curve.c - update curve modifier eval to work with virtual modifiers - update modifier apply to work with curves/surfs - update make parent to also recalc object data NOTE: Although you can turn SB on for curve/font objects at the moment it doesn't really work because they call deform in multiple steps and this confuses SB. Not sure how to deal with atm.
