just to expand on Torsten's challenge:

the GDK offscreen window API has an odd set of signals which can be
fairly tricky:

  (double x, double y) = GdkWindow::from-embedder (double x, double y)
  (double x, double y) = GdkWindow::to-embeeder (double x, double y)

they will require custom marshallers. these signals are required to be
able to implement offscreen containers - that is: widgets that contain
children drawing offscreen. obviously, GtkOffscreenWindow does that for
you already, but it is a top-level (which means that it cannot be a
child of another widget) and it would be nice to be able to have pure
Perl implementations.

ciao,
 Emmanuele.
