We'll now have a more in-depth understanding of user's gestures based on which we can trigger different BrowserToolbar behaviors depending on if the user is scrolling or zooming. The ConstraintLayout parent will still inform us about when the scroll begins and when the scroll ends but then actually incrementally updating the toolbar's translation will be done in response to GestureDetector callbacks. This also allows us to easily differentiate between horizontal and vertical scrolls and only react for the latter. If the user's gestures as inferred as zoom gestures (multi-finger scale or quick-scale) the toolbar should not be animated. This scenario is though affected by the fact that normally scroll gestures have a much higher sensitivity (a 1 pixel movement is enough for a gesture to be considered a scroll gesture) and so it is possible that even in the case of a desired zoom gesture the scroll callbacks will be fired first. When the gesture is identified as a zoom gesture we will immediately snap the toolbar up/down but there might be a minor visual glitch because of this. In an effort to reduce such races between scroll and zoom gestures I've lowered the sensitivity of the ScaleDetector, this having the other effect that multi-finger scrolls must now be more precise. Pinching while zooming will now more often mean a zoom gesture and not animate the toolbar.
