	* libgimpwidgets/gimppreview.[ch]: renamed newly added function to
	gimp_preview_get_controls(). Increased row padding for controls.

	* libgimpwidgets/gimpwidgets.def
	* libgimp/gimpzoompreview.c: changed accordingly.

	* libgimpbase/gimputils.c (gimp_enum_get_value): ref the enum
	class instead of only peeking at it.

	* libgimpwidgets/gimpzoommodel.c (gimp_zoom_button_new): set a
	tooltip on zoom buttons that only show an icon.
