+// will probably have to change in the future.  (The current Mac OS X
+// API is undocumented and was reverse-engineered.)  Until support is
+// implemented in the event dispatcher to keep these events as
+// chrome-only, we must listen for the simple gesture events during
+// the capturing phase and call stopPropagation on every event.
