Currently with module's 7.x-1.0 version:
image edit form is like this in ctools modal ( https://www.drupal.org/files/issues/image-style-applied.png )
In this small image, if we want to change focal point complete opposition to current focal point, it won't show rest of the image.

So i have added one checkbox option that allows to disable image style "focal_point_preview" on edit page.
After applying patch, it will show whole image and we can update focal point in opposite side of image.
