haptic-manager: New object to handle the Haptic DBus interface
To trigger a 200ms rumble at 100%, a 50ms pause and a 300ms rumble at 50%: busctl call --user org.sigxcpu.Feedback /org/sigxcpu/Feedback org.sigxcpu.Feedback.Haptic Vibrate 'sa(du)' org.foo.app 3 1.0 200 0.0 50 0.5 300 To cancel an ongoing pattern: busctl call --user org.sigxcpu.Feedback /org/sigxcpu/Feedback org.sigxcpu.Feedback.Haptic Vibrate 'sa(du)' org.foo.app 0 The API has lower priority than the event based API to e.g. not miss incoming phone calls or cell broadast messages.
