- add the ability to set the vsync delivery rate, when the rate is set to N>1 (ie: receive every N vsync), SF process' is woken up for all of vsync, but clients only see the every N events. - add the concept of one-shot vsync events, with a call-back to request the next one. currently the call-back is a binder IPC.
