+ * Different types of tap-related events that can be sent in

+ * 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).
