	* src/main.c (main): Try harder to find a theme in the event that
	the theme in the preference cannot be found.  Patch from Marcin
	Krzyzanowski.  See #125815.

	* src/place.c (meta_window_place): use "visual" centering for
	dialog placement and clip new dialogs to an xinerama workspace.
	Fix for #118336.
