Re: [pointerevents] Considering adding an API to get pre-coalesced points

Discussed at TPAC f2f, we think we should have an API something like:
```
interface PointerEvent {
  sequence<PointerEvent> getHistoricalEvents();
}
```

Properties:
- Some of the properties would be redundant with the primary event.  
Eg. `pointerId`, `pointerType`, `target` would always match exactly
- `getHistoricalEvents` method on each such object would return an 
empty sequence (but perhaps could throw)
- The primary event always has a timestamp greater than every event 
returned by `getHistoricalEvents`
