BitBLT Operation
Figure E-4: Correctly Performed BitBLT
with Overlapping Source and Destination Locations
The BitBLT engine reads the source data and writes the destination data starting with the right-most pixel
of the bottom-most line. By doing this, no pixel existing where the source and destination locations overlap
will ever be written to before it is read from by the BitBLT engine. By the time the BitBLT operation has
reached step (e) where two pixels existing where the source and destination locations overlap are about to
be overwritten, the source data for those two pixels has already been read.
