	Yes - that will not be for 3.5 though - there are too many issues with
it still I think; it's mostly there for the broadway support (though it
is getting a lot better than it was).

	Right - we don't have an OutputDevice handy there. Of course - it'd be
dead nice if we had a real signal/slot pattern that could be used to
effectively listen for changes in things like this but ... ;-)

	Haha :-) so that is perhaps hard to avoid for the pure gtk+ dialogs
such as the file-picker; and hopefully mostly a problem for testing,
however for our captive widgets we could re-train them with:

	gtk_widget_set_direction

	as/when it changes; and we could use:

	gtk_widget_set_default_direction

	as well I guess for the native dialogs. Arguably we should have a hook
that does that when we change our direction at run-time. Having said
that - the call looks pretty cheap (if there is no change), so we could
call it a lot ;-)

	Cool :-) well, LibreOffice is only awesome & fun because of good guys
like you jumping in and improving it left & right.

	Thanks :-)
