you wanted viewportpx from latlon? well, you got it mister. using a small and but ingenious hack by the astute dr. steven erle, we are able to fix the last remaining (famous last words) kink in the google layer. seems like it should be all a-o-k now. Changed the getLonLatFromViewPortPx() to use the Container as well. Case closed.
