No, xine for instance is updating the entire screen, significantly 
faster than I can do it using gdk. I think this is due to the 
asynchronous nature of the screen updates.

At its simplest, I have some image data in a compressed format (it 
doesn't matter what it is). The size of this image is arbitrary. I want 
to store that image data internally in RGB format and postprocess it. 
Then I want to get it onto the screen at exactly screen size, or some 
user-selected divisor thereof.
