[greatlrd] 20602: fixed working strechblt for all dibxx now. do not say it does not take offset of source and destantion into accunt, it does. left implement CliprRegion. but last no longer black windows with or corupt images showing.

fixed working strechblt for all dibxx now. do not say it does not take
offset of source and destantion into accunt, it does. left implement
CliprRegion. but last no longer black windows with or corupt images
showing.
