[Greeter] Unlocking welcome screen with two fingers doesn't unlock properly

Swipe away the welcome screen with one finger, all works as expected
Swipe away the welcome screen with two (or more) fingers and the welcome screen can get stuck half way off screen.

This has been around a while now. Latest released image (28) has it too.

Setting as Medium since you can easily recover, and it's a rather unexpected use case. Bug nevertheless.

adding the UX project, as i've often wondered about this. Some fidgety people fiddle with their phones in their hands, and are shocked to see they've "unlocked" their phone - whereas, single finger can be filtered as a purposeful interaction compared to a potential multi-finger-accident.
Do we want to keep single finger only?

Works in the latest build

I guess I'll mark this fix released for unity8. There is still an oddity with using two fingers, if you start swiping with one (or two) fingers, then add a third finger holding the welcome screen in place. Release the two fingers, and then the third, and you can sometimes get a stuck greeter.

But I believe that's a separate bug (Saviq filed that?). This bug about just the two finger swipe seems to work fine today.

For the record: you cannot swipe away the welcome screen with 2 fingers. It only accepts single-finger drags.

But after a single-finger drag has started, you can add as many fingers as you want since those new ones will be ignored.
