That will cause race conditions and screen artifacts due to the round-trip 
time to the server: if another window moves over the drawn area while you are 
manipulating the fetched image, then you will get invalid pixels in the area 
that is uncovered.  It is also hideously inefficient.

The Xrender extension and/or Cairo is the correct way to do this, which we 
will tackle only after everything else works correctly.  The work needed is 
mostly in System.Drawing.Xsharp and Xsharp, so it should not affect anyone 
working in System.Windows.Forms or System.Drawing.

Cheers,

Rhys.
