Feature: autocrop (remove whitespace from the edges of an image)? #642
Description
Just finally upgrading from the ancient 3.2.5 version of this app and stumbled across one cropping option that doesn't seem to exist anymore that would be really handy autocrop.
In the old docs, it was defined as:
Remove any unnecessary whitespace from the edges of the source image.
Anyway, it was a handy shortcut that I used to clear background at the edge of portrait-style photos. I've just disabled it, but now have more background appearing in my portrait photos. Are there other ways to accomplish the same thing?
