/// - Only a copy of the selected region is used. The region itself can be selected for any number of other device contexts or it can be deleted.
/// - The SelectClipRgn function assumes that the coordinates for a region are specified in device units.
/// - To remove a device-context's clipping region, specify a NULL region handle.
