I've seen both of them, but each uses Imlib (and I don't want to be
dependend on Imlib if possible - there are Imlib, Imlib2 and GtkPixBuf at
the moment for the same thing, and nobody knows which of them will still
exist in a year :-( ). I think it will be similar with
Gtk::Gdk::Pixmap->create_from_data() but coudln't find out how exactly it
has to be done.

Cheers,
Robert
