//
/// Called by Paint to repaint all of the gadgets, PaintGadgets iterates through the
/// list of gadgets, determines the gadget's area, and repaints each gadget.
///
/// You can override this function to implement a specific look (for example,
/// separator line, raised, and so on).

// clip rect before painting, otherwise just paint. Most gadgets don't
// need this help
