I don't think there is any way to determine between
windows of different types, but I have to admit I
don't really see the need for this capability.

Graphics programs are typically either written in such
a way that they are completely ignorant of where they
are "going" (I.e., they go into PostScript output as
easily as they go into the current graphics window)
or they are written in such as way that you know
*exactly* where graphic output is going (ie., a
widget program).

I think only programs that *hope* they know what
the hell they are doing would benefit from this
feature. :-)

Cheers,

David
