* Added a limited "fast draw" mode to pbvh drawing that tries to limit data sent to the GPU. - Facesets and mask data are disabled. - Indexed mode is forced. - Does not work (at all) for multires. * Finally fixed some outstanding bmesh sculpt undo bugs: - Forgot to mark pbvh nodes to update their bounds, which produced a bug I had thought was caused by something else. - Hopefully fixed a long-standing occasional memory corruption bug.
