Fixes various crashes and redraw problems, most noticeable new feature is that you can now sculpt on a multires mesh with deforming modifiers preceding it. I've left out support for sculpting on multires with enabled modifiers following it, in this case only the base mesh can be sculpted now. The code changes needed to do this are just too ugly in my opinion, would need a more torough redesign which I don't think we should try now. In my opinion this is also not really an important case, since it's going to be incredibly slow anyway to run a modifier on a high res mesh while sculpting. So, to summarize current state: * Fastest sculpting: base mesh with no modifiers or multires with only modifiers preceding it. * Slower sculpting: base mesh with modifiers, depends on the speed of the modifiers. * Not supported: multires mesh with modifiers following it.
