Subject: changed OSystem to allow RBG<->16bit color conversion to be done in
 the backend; after all, the backend 'knows' best what format the overlay
 uses. Default implementations of RBGToColor and colorToRBG assume 565 mode,
 backends other than SDL may want to provide alternate implementations (SDL
 backend already does the right thing for non-565 modes)
