// Modifiers is a bit set of keyboard modifiers held during a key or pointer
// event. ModShift, ModCtrl, ModAlt and ModSuper report held keys; ModCapsLock
// and ModNumLock report the latched lock state. The Renderer reads only
// ModShift and ModCtrl, so lock bits never change shortcuts or text entry.
// The Renderer does not expose modifiers to views: an application that shows a
// lock indicator records the lock bits of Input.Modifiers in its own model.
