This is the default toolbar texture shown in the static layout (surprise!). 
You'll probably want to eventually pipe the active tab's color here.

Oh. I see. I agree, since we don't show the anonymize rect in here it works OK
now, but for using this color for tinting the texture itself on the cc side, the
color should also be piped here.
