Remove "valid" flag from Rect and Point, derive them directly from SDL_Rect and SDL_Point structures, simplify logic. Now x/y/w/h member variables are directly accessible and Rect/Point may be passed as SDL_Rect/SDL_Point via pointer or reference. Change all cases where Null Rects and Points were used to Optional. invalid state related functions like Null(), IsNull() and Get() are now deprecated but are not removed yet for compatibility sake.
