Bug in Cropping

Current situation

1. Create an archetype for hippo version 7.9.4.
2. Add a custom imageset with a variant with unbounded height and upscaling=false (default), see Create a custom image set .
3. Try to crop the image to a height less than the height of the generated variant. This is not possible.

Desired situation

1. Cropping the image to a height less than the height of the generated variant is possible. The same should apply for a situation with unbounded width.
