This class encapsulates a monochrome mask bitmap, where the masked area is black

and the unmasked area is white. When associated with a bitmap and drawn in a device

context, the unmasked area of the bitmap will be drawn, and the masked area will

not be drawn.

This example shows not only how to create a Mask, but the effects of the Device
