Allow zooming with two fingers on touchpads and mobile devices
On touch screens
Pinch to zoom involves using the multitouch parts of the JS API (see here) to track the two finger positions and see how they move relative to each other. There are some StackOverflows posts that may be helpful for this and some JS libraries that can be referenced (without directly stealing their code) but I don't think this warrants adding another dependency to the project, we should be able to implement this ourselves.
On trackpads
We need to apply a speed multiplier (so it doesn't feel so slow) when the Ctrl key isn't actually down, but is being reported as down by the browser lying during a wheel event: https://stackoverflow.com/questions/74312612/trackpad-pinch-causes-wheel-js-event-with-ctrlkey-true-how-to-tell-if-the-u and https://danburzo.ro/dom-gestures/
Hi @Keavon
I want to work on this issue. Let me know the deadline for this Task.
@themujahidkhan Upon taking a closer look at this, I don't currently have the bandwidth to help land this feature since it's not currently a very high priority. Would you mind finding something else please? I removed the Good First Issue task.
