Crop continuously following an indicated subject

It would be very usefull to implement a Crop function that moves the crop continuously attach to an indicated subject

that’s a very particular and sophisticated tracking function in video editing applications

maybe the already existing “stabilization” function could be utilised for that, but it’s still something that is quite alien to the principle of restoration and more in the realm of special effects.

Since it works actually with “stabilization” (that means it defines already a subject in a frame to stabilize around that) it must mot be so complicated to define that manually by the user.
