With an object movie, the panning buttons do not do anything until you've zoomed in. I'd like to be able to gray them out until you've zoomed in, and gray them out again when you're zoomed all the way out. Is this possible?
I edited the original code, although it doesn't work perfectly yet. The view.hfov and view.vfov don't quite work the way I expected. When I zoom in, and then trace their values while zooming out, they are not monotonic. Perhaps someone could make a better suggestion...
