Add pause() function. #84
Conversation
The pause() function allows the user to pause the cropping by unbinding the events but keeping the css, html and data alive. It can be re-enabled by another call to pause(). You can specify a boolean for force the pause or unpause regardless of previous status.
Using hammerJS's .off() does not restore native events and as such
scrolling the on the image on mobile was impossible.
The pause() method now uses hammerit.get('pinch').set({enable: false});
(or true) to correctly toggle HammerJS on and off instead of re-creating
a new instance each time like I previously did.
This required moving some stuff around because there is no such thing as
pausing a receiver withtout HammgerJS.

Reopening with the latest version. This already includes the fix for HammerJS in PR85, but I still provided the PR85 as standalone in case you want to include the fix but not the pause() method. Turns out that HammerJS's .off() method does not restore native events, so scrolling was impossible. I fixed it by using hammerit.get('pinch').set({enable: false}); (or true) in the pause method instead. Since the first version I also added the ability to start the cropbox paused with the "paused" option. Tried it on Chrome, FF, Chrome Android, Safari iOS and IE9 without any issues. |
Added handling of the mousewheel event when using HammerJS. By adding an _unbindMouseWheel() method and calling it as needed in pause().

Hopefully last commit on this: added correct handling of the mousewheel event when using HammerJS. |
