GUI Crop image field - Plugin request I'm just wondering here if something like this is possible. On a website I'm working on for a photographer, he's in need of carefully selecting focal points on his images. 

I'm aware of the focal point plugin, but that is connected to the assets file itself. And not the entry. So basically what I'm asking is

Is it possible to: 


Upload the full source image to assets 
On an entry, select this
image
Have a separate field with a GUI control of the cropping of
selected image from point 2.


Save the entry. And Craft takes those parameters and generates the new image and puts it in the destination folder. So the new cropped image is not in Assets at all.

The reason for this need is because the photographer wants full control of the focal points of each image.

TLDR:
Is it possible to a use something similar to this gui control on a field where an image has been selected, instead of having it directly on the assets file?
