Cropper.js: No smoothing with zoom?

I'm using Cropper.js and wondering if anyone knows if it's possible to stop it smoothing out the image when you zoom in. I want it to stay pixelated because I want to use it to crop video game sprite sheets.

I've actually just worked it out. You can add this CSS:

img { 
    image-rendering: optimizeSpeed;             /*                     */
    image-rendering: -moz-crisp-edges;          /* Firefox             */
    image-rendering: -o-crisp-edges;            /* Opera               */
    image-rendering: -webkit-optimize-contrast; /* Chrome (and Safari) */
    image-rendering: optimize-contrast;         /* CSS3 Proposed       */
    -ms-interpolation-mode: nearest-neighbor;   /* IE8+                */
    image-rendering: pixelated                  /* Confirmed working in Chrome
    }

I found the whole thing minus the last line here but it wasn't working on Chrome so I added the last line found here and now it's working.
