	10	@class wxPaintDC
	11
	12	A wxPaintDC must be constructed if an application wishes to paint on the
	13	client area of a window from within an EVT_PAINT() event handler. This
	14	should normally be constructed as a temporary stack object; don't store a
	15	wxPaintDC object. If you have an EVT_PAINT() handler, you @e must create a
	16	wxPaintDC object within it even if you don't actually use it.
	17
	18	Using wxPaintDC within your EVT_PAINT() handler is important because it
	19	automatically sets the clipping area to the damaged area of the window.
	20	Attempts to draw outside this area do not appear.
	21
	22	To draw on a window from outside your EVT_PAINT() handler, construct a
	23	wxClientDC object.
	24
	25	To draw on the whole window including decorations, construct a wxWindowDC
	26	object (Windows only).
	27
	28	A wxPaintDC object is initialized to use the same font and colours as the
	29	window it is associated with.
