Re: [pointerevents] tiltX and tiltY aren't as helpful as just having altitude angle (#274)

This also means an app that expects to get values for `twist` (say with a stylus that does have an orientation around the Z axis when standing straight up), won't work correctly with an app that doesn't provide values. i.e. a painting app would orient the nib shape around the twist, but instead should use tiltX and tiltY.

I could be wrong! It's a bit confusing.

Either way, I still think the idea of a polar rotation from the Y-Z plane (called `azimuthAngle`) and the smallest angle between the surface and the stylus (called `altitudeAngle`) makes more sense for apps.
