Fix for mobile zoom issues

[mkondel]

• Problem:
  Mobile users can zoom into an open image by pinching. Any sliding left or right will trigger the swipe event. It is impossible to look around the zoomed in image, it will always load next/prev photo.
• Suggestion:
  A simple solution could be to disable the swipe events while in a zoomed in state. How could this be done in photobox.js?

@yairEO, is this something you have encountered?

It is a problem to detect if the pinch caused the zoom (and not setting the zoom manually in the browser or with the mouse CTRL+mousewheel)

There are discussions about it here:
