	* libgimpwidgets/gimppreview.c: connect-after to "realize" and
	"size-allocate" signals of the preview area and call the
	set-cursor method from the callback.

	* libgimpwidgets/gimpscrolledpreview.c: no need to explicitely set
	the cursor now that the virtual method is used correctly.

	* libgimp/gimpzoompreview.c: implement set-cursor and set the move
	cursor in accordance with the zoom factor.
