just curious, are the fre_ dimensions still used? If not, we should remove them
as well.

Yeah, they are all used.

I should have a CL in hopefully tomorrow with a redo of the fre screens (because
at the moment we have three screens (terms of service, data saver, account sign
in) that look similar but actually share very little code so getting them to be
laid out the same is difficult. Would you like me to cc you on it?
