QuickZoom zoom level after zooming in

[tobrun]

If you use the quick zoom gestures (double tap and hold) and you zoom based on y-amount of pixels and later zoom back in with same y amount, you don’t end up and the initial zoom level.

Debugging the issue I noticed that underlying ScaleGestureDetector can return suspicious values

D/MapGestureDetector$Scal: scale: factor - 1.1339383
D/MapGestureDetector$Scal: scale: factor - 1.0364736
D/MapGestureDetector$Scal: scale: factor - 0.84954655
D/MapGestureDetector$Scal: scale: factor - 1.3086545
D/MapGestureDetector$Scal: scale: below 0
D/MapGestureDetector$Scal: scale: factor - 0.84537005
D/MapGestureDetector$Scal: scale: factor - 0.8748795
D/MapGestureDetector$Scal: scale: factor - 0.94667435
D/MapGestureDetector$Scal: scale: factor - 1.0942392
D/MapGestureDetector$Scal: scale: factor - 1.2115576
D/MapGestureDetector$Scal: scale: factor - 1.2501236

adding clamping to that can result in uneven zoom effect.

We should tackle this issue with mapbox/mapbox-gestures-android#15.

Decreasing the deadzone in mapbox/mapbox-gestures-android#30 helped a lot and I'm not feeling like this one is an issue anymore.
@tobrun, could you re-check release-boba on a device that you used for testing in the OP?
