Cool, if we can have this added to an updated DeviceOrientation spec
then that's definitely the best solution here.

Though the issue above seems to suggest that the spec would define
that the existing alpha/beta/gamma properties would be redefined to be
screen-relative rather than device relative. Is that really going to
be web compatible?

I don't think mozilla would feel comfortable leading with such a
change given our limited influence for mobile content. But if browsers
with bigger mobile marketshare make such a change we'd definitely
follow. Do you have any indication that there's interest in that?

A safer option seems to be to introduce
screenAlpha/screenBeta/screenGamma (or something similarly named) and
make those relative to the screen. That is something that I'm fairly
sure I can make happen in Gecko.
