	* libgimpwidgets/gimppreview.[ch]: added a hbox to the table and
	the "Update Preview" checkbutton there. Added a function to access
	this control box. Increased default size to 200.

	* libgimpwidgets/gimpscrolledpreview.[ch]: added function
	gimp_scrolled_preview_set_policy() to control when the scrollbars
	should be shown.

	* libgimpwidgets/gimpwidgets.def: updated.

	* libgimp/gimpzoompreview.c: pack the zoom buttons into the
	preview's control box. Commented out the label, it shows a bogus
	zoom factor. Set scrollbar policy to ALWAYS to avoid resizing.
