http://www.w3.org/TR/2013/WD-pointerevents-20130115/ proposes "In order
to facilitate differentiating button state transitions in any pointer
event (and not just pointerdown and pointerup), the button property
takes on a new value when no mouse buttons are depressed" specifically
the value -1 would be for "Mouse move with no buttons pressed". So, for
'mousemove' with no button pressed you will get MouseEvent.button == 0,
while for "pointer events" you get MouseEvent.button == -1?
