// A note about NativeEvent and NativeEvent2.
// 1. Eventually TOOLKIT_VIEWS will converge on using XEvent as we remove
//    Gtk/Gdk from the stack.
// 2. TOUCH_UI needs XEvents now for certain event types.
// 3. TOUCH_UI also needs GdkEvents for certain event types.
//
//    => NativeEvent and NativeEvent2.
//
// Once we replace usage of Gtk/Gdk types with Xlib types across the board in
// views, we can remove NativeEvent2 and typedef XEvent* to NativeEvent. The
// world will then be beautiful(ish).
