Do we need iron-image for something too? Can you add it to the CL description?

[Dan Beam, 2015/07/29 23:35:58]

¯\_(ツ)_/¯

presubmit tell me do something. me do.

(I assume it's a dependency)

[michaelpg, 2015/07/30 03:17:09]

if presubmit tells you you needed it, it's a dependency.

the idea is if an element suddenly starts pulling
ThirdPartyPatentedCopyrightEvilLicenseWidget, we'd notice (see:
iron-ajax/bower.json, which pulls polymerlabs/promise-polyfill, which is an
unsanctioned copy of some random dude's copyrighted code which would have
required an additional LICENSE file had we shipped it, not to mention
open-source and security reviews)

dbeam: did you forget to git add -f paper-menu-button and whatever dependencies
(like iron-image)?
