OK; that even handles the case where an XDRIVER window is resized
interactively.

Although, technically that isn't guaranteed to return the actual size
of the window, as it's reading a pad (property list) which is set by
clients rather than the actual dimensions, but the information will
probably be correct in practice.

It's certainly better than using xwininfo, which will fail completely
in some cases.

Does anyone feel like modifying tcltkgrass to use that? The use of
xwininfo is one of the primary obstacles to using the native
MacOSX/Aqua version of Tcl/Tk for tcltkgrass.
