Pulling in from what I wrote before. 

Currently we have a section on Icons in reference to Documents, Applications,
Toolbars, and Menus.  I'm wondering if Application dialogs, such as print
dialogs, are special enough cases were we'd want to represent them with a
gtk-print icon instead of using the application or document icon.  This applies
to dialogs are of standard type: open, save, and print; and even probably alert
dialogs as well, but I thought they already did this.

We have a couple cases here:
   Use the Application Icon for the dialog window.
     1) In the case of a document centric app - the visible icon may be
different from the applications icon.
     2) In the other case - it uses the same app icon for all the dialog windows
   Use the Document icon for dialog window
        In 1) the visible icon is the same as the dialog
        In 2) this case doesn't really exist

My view is that keeping consistant icons is the best method.  Using the
Application icon can be a good method, except in the case of document centric
apps where the icon doesn't relate to the document.  So it might be good to use
the document icon, however some documents don't have icons and we fall back to
the app icon which doesn't really relate as well to the dialog or the document.

My feeling is that going with a standard 'print' icon for the printer dialog
everywhere, as well as an 'open' icon for the file open dialog, and so on would
make the most sense.  I need to figure out a little bit more of the consequences
on the entire desktop if this is done, but on a first pass this seems a
reasonable way to keep these dialog icons somewhat more sane.

We don't recommend window icons any more.
