Incorrect image size after crop

[Jakooth]

For example try to crop image with size 2000x1300 to 1920x1080.
The result will be image with size of 1919x1279.

This is fixing the problem on line 300:
--$optimalWidth = $dimensionsArray['optimalWidth'];
--$optimalHeight = $dimensionsArray['optimalHeight'];
++$optimalWidth = ceil($dimensionsArray['optimalWidth']);
++$optimalHeight = ceil($dimensionsArray['optimalHeight']);
