Given that this is set based on the elment's id, should this parameter be called
id as well?

[Zhen Wang, 2014/11/06 17:59:26]

I see your point. 

I use "name" here because the transition element will be eventually passed to
Chrome for Android Java side and be used as the name of the transition element
with Activity Transitions API in Android 5.0. So I guess it is natural to use
"name" as the variable name.

[Nate Chapin, 2014/11/11 00:28:17]

Hrm. I guess consistency trumps having a sane name internally, but I'm still
just a little grumpy. :)

[Zhen Wang, 2014/11/11 15:12:20]

I see. Using "id" now.
