Add QWheelEvent::inverted()
Some consumers of wheel events need to know if the
scrolling direction is inverted in order to provide
consistent behavior.
For example, the scrolling direction of a horizontal
slider should not change when the user toggles the
"natural scrolling" setting on OS X. In this case
the inverted bit will change state and the slider
can compensate.
This change adds a bit to QWheelEvent and sets it
on OS X.
