This got me thinking that most of the time the problem with the WYSIWG
editor being displayed all the time was that a lot of the time it screws
up data that wasn't supposed to be HTML to start with.  

I've posted an alernative solution here that I've detailed in the
following issue:

Basically it's to standardize how we tell the forms api and therefor
contrib modules, what kind of data is supposed to be in the text area.
Works for Rich Text editors, Color pickers, CSS editors, etc.
