swipe-to-dismiss from top or bottom?

Awesome job on this, easily one of the better RN image viewers out there right now!

I am rendering my image in a modal (iOS) and I noticed that I can only swipe to dismiss by swiping upwards, not downwards.

Would it be possible to make the swipe-to-dismiss direction user configurable?

I will write a patch for this soon in my own app, but all you need to do is just copy the threshold for up in the same way as down, should be pretty straightforward.
