Decals should be drawn above all platforms, so that you can place a waterfall above a platform_b entity, eg; to make a cave/room where water is present.
However, decals have a spinning graphic at the top, which should be placed behind platform edges.
Possibly it could be done by "scissoring" the rotating sprite, in the case of a waterfall, and then simply drawing all decals above platforms.
