Re: Copying X pixmap.

[Douglas Ian Linder <linderdi cs curtin edu au>]

If nothing else works you can make sure GTK does not draw over your
data by using a non-pending GTK call (like gtk_main_iteration_do())
and only manipulate the window using XLib directly between calls
(you are certain it cannot overwrite your window then). Probably
a bad way of doing it, but you can be certain it works.
