// AbstractHapticGamepad is a base class for gamepads that support dual-rumble
// vibration effects. To use it, override the SetVibration method so that it
// sets the vibration intensity on the device. Then, calling PlayEffect or
// ResetVibration will call your SetVibration method at the appropriate times
// to produce the desired vibration effect. When the effect is complete, or when
// it has been preempted by another effect, the callback is invoked with a
// result code.
//
// By default, SetZeroVibration simply calls SetVibration with both parameters
// set to zero. You may optionally override SetZeroVibration if the device has a
// more efficient means of stopping an ongoing effect.
