I guess apps that want the best support across server generations are
supposed to know they can ignore legacy scroll by virtue of the
POINTER_EMULATED flag? If yes, shouldn't the flag be always set on
either the axis updates or the button events?

I further guess that the non-raw scroll events will still be adding up,
is that intentional?
