	2
	3	This class encapsulates a monochrome mask bitmap, where the masked area is black and
	4	the unmasked area is white. When associated with a bitmap and drawn in a device context,
	5	the unmasked area of the bitmap will be drawn, and the masked area will not be drawn.

	16
	17	A mask may be associated with a \helpref{wxBitmap}{wxbitmap}. It is used in \helpref{wxDC::Blit}{wxdcblit} when
	18	the source device context is a \helpref{wxMemoryDC}{wxmemorydc} with wxBitmap selected into it that
	19	contains a mask.
