aspectRatio and minSize not working correctly

[CapnMarius]

The combination of aspectRatio and minSize is buggy when the ratio is vertical.

cropper with
aspectRatio: 1.3333333333333333
minSize: [ 300, 400, "px" ]
startSize: [ 1200, 675, "px" ]

The minimum crop result should be 300 * 400
But the cropper "snaps" from 400 * 533 to 300 * 533

I fixed it.
The constrainToSize function in box.js has a bug on line 212.

minHeight = minHeight * ratio;
must be
minHeight = minWidth * ratio;
