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

`twist` is defined as "The clockwise rotation (in degrees, in the range of [0,359]) of a transducer (e.g. pen stylus) around its own major axis".

Unless I'm misunderstanding, this value would always be zero for an Apple Pencil. The stylus's own major axis is irrelevant to this device - what's important is how the stylus is oriented to the surface.

I think polar coordinates make much more sense than a tiltX and tiltY in applications (and it's only the angle part of the polar coordinate that matters).
