ardour/gtk2_ardour/panner2d.h
David Robillard 05283a6339 Only use ArdourDialog (and thus Gtk::Dialog) for actual dialogs.
Fixes #4364.

I havn't fully tested every single dialog and window (heck, I don't even know
how to get at half of them), and there may be some packing niggles, but this is
the bulk of the work.  The Gnome 3 kiddies can close their dialogs now, anyway
:)
