Draw on root window

[Magnus Schmidt <yog post1 com>]

Hi there,

 I'm fairly new to gtk-perl, and I stumbled over a problem where I could not 
find any answers in the archives or the net.

For a xscreensaver-hack I need to draw onto the X root window, but I do not 
know how to do this. I've found some hints to call GDK_ROOT_PARENT() but I 
wasn't able to find this Macro in the perl bindings. Is this somehow possible 
with perlgtk ?

I first tried to use a 'popup' window (I know, it is not supposed for this), 
but then I didn't receive any keyboard-events any more. On another try I 
wasn't able to get the correct call for gdk_window_set_decorations(...) ?!

Thanks,
Magnus
