This is really cool! I'd be interested in seeing what it looks like to fully drag the image 180 degrees (but can't because the camera resets as soon as the mouseup event fires). Would you accept a small PR to the demo page which does this via a control button instead of on mouseup?

Thanks! Actually I just pushed a fix to make the drag work outside the canvas. No idea why it wasn't that way to begin with.

The really cool thing someone suggested back in the day was, to have it try to match two different images from two different angles. But I never quite found the time to tackle that ;D
