Can we not copy these values to three places?

[Bobby Powers, 2013/03/21 17:08:43]

Copying is what Elliot originally suggested, and there is already a ton of
duplication among the various native_theme implementations (TextButton colors
are currently the same between _gtk and _win, for example).  What I think would
be best is to commit this as such, and clean up all of the duplication in a
follow up commit.
