Describe the solution you'd like
It would be good to have gesture-based two finger zoom in addition to existing one-finger pan.

Describe alternatives you've considered
Current key-based zoom is less convenient, as is "zoom to mouse rectangle"

Additional context
npm has an easy to use (I expect) package
https://www.npmjs.com/package/pinch-zoom-js

Or, a complete implementation based on pointer events would be possible, but a lot more work.

Pinch to zoom support would also be useful for laptop touchpads as it is more intuitive than Ctrl+Two finger scroll
