	* app/gui/file-new-dialog.c
	* app/gui/offset-dialog.c
	* app/gui/preferences-dialog.c
	* app/gui/resolution-calibrate-dialog.c
	* app/gui/user-install-dialog.c: replaced some more pixel sizes by
	char sizes. Tweaked table spacings. Mnemonics.

	* app/gui/info-dialog.[ch]: internal cleanup.

	* app/gui/resize-dialog.[ch]: same here. Removed the "cancel_cb"
	from the API and simply destroy the dialog on "Cancel". Makes the
	dialog construction less weird.

	* app/gui/image-commands.c
	* app/gui/layers-commands.c: changed accordingly. Same cleanups
	as above.
