-// Wrap a "native" ui::Event in another ui::Event & dispatch it.
-//
-// This is really unfortunate, but exists for two reasons:
-//
-//   1. Some of the ui::Event constructors depend on global state that
-//   is only used when building from a "native" event. For example:
-//   last_click_event_ is used when constructing MouseEvent from
-//   NativeEvent to determine click count.
-//
-//   2. Events contain a reference to a "native event", which some code
-//   depends on. The ui::Event might get mutated during dispatch, but
-//   the native event won't. Some code depends on the fact that the
-//   "native" version of the event is unmodified.
-//
-// We are trying to fix both of these issues, but in the meantime we
-// define NativeEvent == ui::Event.
