[Feature]: Panning past image edges in Gallery

[janpe]

Summary

Hi! I'd like to be able to zoom in on an image and then pan it past the edges of the screen. For example if there is something all the way in the corner of the image that I want to zoom in on.

Expected API

Maybe add a prop for percentage of the screen dimensions that I can pan past. For example if I give 50 value for the prop then I can get a better look at the top right corner (50% from the top). Not sure if it is a good idea to be able to go past the edges in the direction to the swipe from image to image. I'll attach an image to clarify.
