As discussed offline, I think keeping this state per-frame is going to cause
bugs in cases where the point moves between iframes.  It's a pre-existing issue
with the PointerEventManager though, so I'd suggest filing a bug for moving
PointerEventManager from EventHandler to FrameHost and adding a TODO referencing
that bug here.

[Navid Zolghadr, 2016/03/01 20:46:05]

I will file that bug but I believe the TODO belongs somewhere beyond this
particular function and this change. But if you still like me to add the TODO
here I'll add it.

[Rick Byers, 2016/03/03 16:35:45]

Sure, that's fine.  I expect this all to change relatively soon so the TODOs
don't matter much (but the bugs tracking our planned work do).
