Normally, i'd say "make them upgrade -- nobody should be using old 
versions of the bindings, as we support all stable versions of gtk+!"  
but we've already played our API Freeze Break card, so there's very 
little chance of that patch making it into 1.080.  :-(

Maybe.  Need more info.  What are you trying to make?  (Especially 
intriguing since you say GnomeCanvas is too slow for this purpose...)

One possible solution, if you can use images on disk:

   my $rc_style = Gtk2::RcStyle->new;
   $rc_style->bg_pixmap_name ('normal', 'path/to/image.xpm');
   $widget->modify_style ($rc_style);

Another possible solution:  make your own widget.  You'll get complete 
control over the gdk window and can keep gtk+ from blowing away your 
backing pixmap.  Since the $widget->window method currently suffers the 
same malady as $style->bg_pixmap (that is, bound as an accessor, not as 
a mutator), this may prove difficult.
