Support for custom widgets

[Etienne Grossmann <etienne anonimo isr ist utl pt>]

  Hello,

  I was wondering how to access in perl a widget that is not in the
standard gtk distribution, such as gtkdatabox?

  I tried adding a .xs file in Perl-Gtk-0.7004/Gtk/xs/ and fiddling
around, without success.

  Should I have instead created a separate directory, like GtkGLArea?

  If I succeed, should I try to write a "Using a custom widget" entry
for the gtk-perl tutorial?

  Cheers,

  Etienne
