If i dont strip the alpha channel (by hand more or less) and just create 
a new Gdk::Pixbuf from the buffer with has_alpha set to false,
the picture is mainly b&w and some of the right part of the picture is 
cut off.
If i set has_alpha true, then the the Gtk::Pixbuf wont draw... the 
drawable will just be blank/invisible though the size seems to be correct.
