	3	A wxPaintDC must be constructed if an application wishes to paint on the
	4	client area of a window from within an {\bf OnPaint} event.
	5	This should normally be constructed as a temporary stack object; don't store
	6	a wxPaintDC object. If you have an OnPaint handler, you {\it must} create a wxPaintDC
	7	object within it even if you don't actually use it.
	8
	9	Using wxPaintDC within OnPaint is important because it automatically
	10	sets the clipping area to the damaged area of the window. Attempts to draw
	11	outside this area do not appear.
	12
	13	To draw on a window from outside {\bf OnPaint}, construct a \helpref{wxClientDC}{wxclientdc} object.
	14
	15	To draw on the whole window including decorations, construct a \helpref{wxWindowDC}{wxwindowdc} object
	16	(Windows only).
