	* app/dialogs/Makefile.am
	* app/dialogs/image-scale-dialog.[ch]: a wrapper around the scale
	dialog that takes care verifying the user input and optionally
	asking for confirmation. Most of this moved out of image-commands.c.

	* app/actions/image-commands.c: use the new image scale dialog
	even though it doesn't allow to edit the resolution yet. That's a
	temporary regression that will get fixed soon.

	* app/actions/layers-commands.c: cosmetics.

	* app/dialogs/scale-dialog.c (scale_dialog_reset): also reset the
	resolution.

	* app/widgets/gimpsizebox.c: fixed cut'n'paste error.
