That's how I handle things like properties dialog boxes. The display
windows, however, are different in that there can be more than one
open at a time, and I have no way to predict how many the user would
like to have open. Currently, I'm forced to call glade_xml_new for
each new display window the user would like. If there was a clone
function, though, I could have done something like create a window on
startup, then clone it for each new window that the user wanted.
