added VOID__DOUBLE_DOUBLE marshaller.
* libgimpwidgets/gimpwidgetsmarshal.list: added VOID__DOUBLE_DOUBLE marshaller. * libgimpwidgets/gimpzoommodel.[ch]: new signal: "zoomed", emitted when the zoom factor changes. This signal have the old factor and the new factor as argument. * libgimp/gimpzoompreview.c: use the "zoomed" signal instead of the "notify::value" one. This allow to use the old and new factors to keep the preview centered on the same point.
