This is similar to what I needed to put a jpg loaded by gdk_imlib
into a GtkPixmap. I wound up calling 

gtk_object_set_data("gtk-colormap", gdk_imlib_get_colormap());
gtk_object_set_data("gtk-visual", gdk_imlib_get_visual());

between gtk_window_new() and gtk_widget_realize(). Doing
this seemed like a hack. Especially since those strings are
defined in the .c files instead of the header.

(Owen: this is similar to the example from the imlib manual you
 helped me get working )

Is there an easier way to do this or should there be a way to 
set the visual/colormap for a GtkWindow in an easier fashion?

Did this not come up before because most X-servers on Linux have
only one visual depth? One nice thing about Solaris's X-server is 
support of multiple color depths. I just wish it wasn't so easy to
crash. (No crashes from gtk in many months, but I've had my share)
