	* app/commands.c
	* app/layers_dialog.c
	* app/resize.[ch]: new scale/resize ui:
	Use size entries instead of text entries, chainbuttons instead of
	check buttons. Put the stuff into frames. Added labels for the
	original width and height.
	It's possible to change resolution/unit now, please test if it
	does the right thing.

	* libgimp/gimpsizeentry.c: allow lower == upper when checking
	boundaries.
