There can be multiple canvas windows open at a time, and we would want
the dialog windows to be 'transient for' all of them. ie. whichever
of the canvases is clicked on, we want the dialog window(s) to be
brought to the front as well. Is it possible for a dialog window to
be 'transient for' more than one window at a time?

But then all the dialog windows would appear in the task bar wouldn't
they? What I'm wanting is for them to not take up space in the task
bar (for they are pretty much useless without a canvas window also
being shown), but for them to pop up whenever any of the canvas
windows is clicked on. This is exactly what metacity is doing, by the

$ xprop|grep -i -e transient -e window_type
_NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_UTILITY
