Zealous cropping supports repetition of a single colour
Operating System: (if feature is platform specific)
Description of the feature
Zealous currently cops away horizontal or vertical lines which are 100% made of the current background colour.
In practice, pictures that have a lot of gaps also have a lot of lines.
