== Clarify the button value for mouse drag ==
The current spec wording suggests that the |button| value indicates 
"the last button changed" (like MouseEvent). On the other hand, the 
current Edge behavior suggests that |button| is "the button change 
that triggered the current event". The latter makes more sense since 
it makes it easier to differentiate between
- a pointermove fired through a button activity (chorded button 
press/release), and
- a pointermove fired through a non-button change (position, tilt, 
pressure, etc).

This patch proposes a spec wording change based on the Edge behavior.
