Hey there! Thanks for this library, it's been a lifesaver. I've been working on a pretty basic implementation of a pinch-to-zoom gesturable, taken almost verbatim from the example on the homepage. However, event.ds (the delta of the scale of the gesture) seems to be somehow based on the initial size of the gesturable. That is, when the initial size of the gesturable is fairly small, during the gesture the pinchzoom works as I would expect, and scales linearly. However, if I make one gesture to increase the size a significant amount, any gesture I make to decrease the size has an incredibly small event.ds, and therefore takes multiple gestures to return to its original size (whereas it took a single gesture to get to that large size). Is there a known workaround for this?
