Hello and thanks for your efforts in this great library. Today i researched on some points in case of responsive images. One interesting feature for a resizing library would be the option to define a focal point. If an image gets resized, this point ensures that the "important" part of a picture is still included. I know there's an option "anchor" that goes in this direction, but support for a focal point would be much better. Here's some info from another Software that supports such an option:

Thanks.
