can we make this USE_AURA?

[scottmg, 2012/11/12 18:03:53]

Done.

[scottmg, 2012/11/12 18:20:30]

Oops, USE_AURA doesn't work on linux_aura. I'm not sure if there's a better way
to get an ash window without an ash:: here?

[Ben Goodger (Google), 2012/11/12 18:26:25]

hrm. I guess we're not building ash yet on linux. use_ash is fine then.
