Babylon.js only recognizes vertical pinch, not horizontal pinch

[jdm]

When using the three.js paint demo, my right hand can use a horizontal pinch gesture to start painting (but the left hand does not appear to recognize a horizontal gesture, only the vertical one). However in Babylon.js, only the vertical pinch is recognized by both hands.

This seems less cut and dry than I though. Babylon's left hand doesn't appear to recognize the horizontal pinch either, and I can definitely make a horizontal pinch successfully on occasion with the right hand.

This is very weird, because all we get from the system is "did a pinch happen", we do no further analysis.

Note: the hololens' ability to detect pinches can depend on the backdrop, perhaps your typical working space has a varied background that favors gesture detection on the right hand.

I think the OpenXR demo app (inside the openxr runtime app) displays pinches when they occur, do you want to try with that and see what happens?

Babylon's new select event detection may also be wonky
