Remarks

Adds a rectangular region to the bitmap.

With this method, you can either replace the current region or create a complex region by setting a Boolean flag that determines how the added region interacts with the existing region. For possible values, specified in the uCombineMode parameter, refer to Flags for Setting a Region.

Coordinates are unscaled relative to the LEAD bitmap in memory. The unit of measure is pixels.
