Blender Git Commit Log

matrix.scalePart() was never returning negative values, even tho its impossible to get correct negative scale/rotation values from a matrix, blender gets these values in apply_obmat (editobject.c) in a way that keeps the transformation the same at least.

copied the code from apply_obmat to be used by matrix.scalePart() ob.getSize('worldspace'), this makes the hack I committed to FBX before not needed (rolled back in this commit)
