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

> so, for both backwards compatibility and "giving developers what they want" (though, is this backed up by data on developer wants? or purely on "since on this platform there's only this type of data, this is what they want"?), would a way forward be to provide these as additional properties? which would then require browsers to backfill/calculate the data that isn't currently provided by the low-level APIs?

Good question. I imagine there is a legacy bias "I wrote this decades ago on an SGI and X Windows has always provided tilt so I dealt with it".

Proving both has "pain equity" since both platforms need to calculate something. Platforms with tilt need to computer altitude azimuth, and platforms with altitude azimuth need to compute tilt. ;-)
