I was confused by these checks, until I understood your comment about them being
mac only. Could 'chrome_material' be better named? Perhaps chrome_material_mac
given they are mac only now? Same comment for target names and theme_resources.

[Evan Stade, 2016/05/19 23:20:10]

They're going away even on mac, so is_mac is temporary. Would a comment here or
somewhere be helpful iyo?

I // TODO(estade): temporary, will remove soon, see http://XXXX
would be helpful

[Evan Stade, 2016/05/20 16:54:51]

Done.
