     // TODO(wittman): remove once the new visual style is complete

[sky, 2013/12/02 21:41:46]

Is the TODO still appropriate?

Whoops. I missed this before landing, sorry. Checked with wittman@, and the TODO
applies only to SetProperty, so it should be removed. I will put up a follow-up
CL shortly.

         widget->GetNativeWindow(),
         platform_util::GetParent(widget->GetNativeView()));
