Hmm, do we want this in events_base? Android doesn't use this, does iOS or Mac?
When we do move it to events_base, I think I'd prefer that all platforms use it
for the relevant constants.

Let's leave cleaning that up until we sort out the gesture_config_helper*
locations.

I think it's reasonable to leave that until after this has landed?

[jdduke (slow), 2014/05/05 17:52:48]

sgtm, maybe file a bug if there's not one already?

Bug is https://code.google.com/p/chromium/issues/detail?id=339203.
