what controls zoom and pan speed?
I am zooming out and vertically and horizontally panning on a still image; as the timeline runs, the rate of the zoom/pan increases so that it's a good bit faster towards the end. What controls the *rate* at which the pan and zoom occur and why isn't it even between those 2 points? My assumption is it has something to do with how Position and Scale work together but I really don't know. Thank you!
