//A DrawObject is parallel to PWidget, but specific to drawing 
//primitives.  It differs from PWidgets because it doesn't need to be
// directly tied to a SDL_Surface.  If it is constructed with a NULL surface,
// it creates one itself, and cleans up after itself.  If it is created
// with a widget passed in, it does not destroy that widget when it is 
// destructed.  Thus, you can 'draw' on any other widget you want.
