Simulation support:

None. This function is mandatory for all drivers.

Description:

GreSetBitmapBits transfers bit-map data from application storage into the specified bit map or DC.

This function must be supported by the presentation driver. GreSetBitmapBits is called from the function GpiSetBitmapBits, and is used to transfer bit-map data from the device context to application storage. This function can be handled by bit-map simulation.
