 * Different types of tap-related events that can be sent in
 * the HandleTap function. The names should be relatively self-explanatory.
 * Note that the eLongTapUp will always be preceded by an eLongTap, but not
 * all eLongTap notifications will be followed by an eLongTapUp (for instance,
 * if the user moves their finger after triggering the long-tap but before
 * lifting it).
 * The difference between eDoubleTap and eSecondTap is subtle - the eDoubleTap
 * is for an actual double-tap "gesture" while eSecondTap is for the same user
 * input but where a double-tap gesture is not allowed. This is used to fire
 * a click event with detail=2 to web content (similar to what a mouse double-
 * click would do).
