Rewrite of the art system

Yeah, PR3 has this and it's great (although the menus get in the way so you have to do it on layer 1 and switch to bg layer which is annoying imo)
if we had bg layer on PR2 have it so when you are drawing the UI disappears or goes transparent quite a bit

RMX added the ability to hide the menus with a shortcut, one for the left side and one for the right, so the menus getting in the way is no longer an issue. Probably still better to draw in layer one though, since you can zoom in on anywhere for the background you want to draw.
