Companion

Disables overzoom effects entirely. Content will stop zooming as soon as it reaches its limits, without any additional visual feedback or elasticity.

Does not limit over/under zooms in any manner. Content will zoom in a free-form manner even when it goes beyond its limit (until the gesture is released).

Applies a rubber banding effect to zoom gestures when content is zoomed beyond its limit as a form of visual feedback that the content can't be zoomed any further.
