Double tap has double logic and works incorrect

[comm1x]

At first, thank you for your library!

Double tap in FrescoImageViewer has double logic: zoom-in/zoom-out with fixed-step and zoom-in/zoom-out with single-finger-pinch.

In Google Maps, app waits a little delay. If there was no interaction, app recognize gesture as fixed-step. If interaction was, recognize as single-finger-pinch.

FrescoImageView fires both. So when I do signle-finger-pinch (double tap with active last tap): app do zoom-in (sometimes zoom-out) and then recognizes all my finger moves as zoom.

I think, we should allow to disable some of this logics, or configure long of delay.

Hi @comm1x and thank you for such interesting observation! :)
Let me know when your PR for PhotoView library will be merged and I'll be able to update it for FrescoImageViewer library. Cheers!
