Removed Wait_VBL. Was only used for slowing down things. Used SDL_Delay(1) instead, which let the OS handle other things. We should get about 10-20ms latency with that. Scrollbars may be slightly faster. The only place where this could be a problem is discontinuous freehand. If the current way it works isn't good, look at the "Chrono" functions (like the spray) instead.
