*
* - focus stuff
* + `last focused' for nasty sessionsaver hack
* + set focus into a sensible control to start with
* + perhaps we need uc->primary as the right widget to
* forcibly focus?
* * no, because I think the right widget to focus with
* radio buttons is the currently selected one. Hmm.
*
* - dlg_error_msg
*
* - must return a value from the dialog box!
* + easy, just put it in dp.
*
* - font selection hiccup: the default `fixed' is not
* automatically translated into its expanded XLFD form when the
* font selector is started. It should be.
*
* - cosmetics:
* + can't we _somehow_ have less leading between radio buttons?
* + wrapping text widgets, the horror, the horror
* + labels and their associated edit boxes don't line up
* properly
* + IWBNI arrows in list boxes didn't do such a bloody silly
* thing (moving focus without moving selection, and
* furthermore not feeding back to the scrollbar). And arrows
* in the treeview doubly so. Gah.
* + don't suppose we can fix the vertical offset labels get
* from their underlines?
* + why the hell are the Up/Down focus movement keys sorting
