Summary: Clear bug and Blit bug fixes

Initial Comment:
First Fix: After trying to figure out how WHITE AND
BLACK = WHITE I realized that Blit was ignoring the
logicalFunc argument.  One of the code paths in DoBlit
had a hardcoded SRCCOPY.  Changed it to dwRop like the
rest of the code paths.

Second Fix:  I always noticed that you cannot clear a
DC once you have called dc.SetDeviceOrigin() because it
still clears around 0 and not at the new 0 point.  I
changed it so it draws a filled rect at
-deviceOriginX,-deviceOriginY instead of 0,0.
