The ClipRect and BitMap and used for rendering the requester
If the BitMap plane pointers are non-zero, this tells the system that the image comes pre-drawn (if the appliprog wants to define it's own box, in any shape or size it wants!); this is OK by Intuition as long as there's a good correspondence between the image and the specified Gadgets
