You can't really speed up the uploading of bitmaps to the X server when 
the state has been changed to DIB_Status_AppMod since you can't tell 
what has changed, but I do think your idea is good for downloading the 
bitmap from the X server when in the GDI state. I would maybe suggest 
making the changed rect an argument to the coerce function though so it 
isn't possible for GDI functions to forget to do it before calling coerce.
