Storing the resId feels implementation specific (ie: The LayerTitleCache needs
it, but not the ResourceManager).  I'm fine with it being here for now, but we
should see if there's a better way to do this in the future.

[Jaekyun Seok (inactive), 2014/11/18 23:34:02]

I will do that later.

This should be final so we can't call new again and churn GC.

[Jaekyun Seok (inactive), 2014/11/18 23:34:02]

Done.

[David Trainor- moved to gerrit, 2014/11/18 18:53:53]

Static should go up top (sorry I missed that downstream).

[Jaekyun Seok (inactive), 2014/11/18 23:34:02]

Done.
