I am already post the same issue in FrescoImageViewer: stfalcon-studio/FrescoImageViewer#65
We need to separate two gestures:
completed double tap: touchDown, touchUp, touchDown, touchUpsingle-finger-zoom: touchDown, touchUp, touchDown, drag, touchUpLike a Google Maps, we do not need to apply autoscale in 2nd case.
I am suggest possible a bit dirty solution: with flag and 50ms delay (50ms like Google Maps).
