Preparation for multi-components Note that this had to rename one instance of TextStyle because it conflicts with the struct of the same name used in the FontSettings in the style. This wasn't a problem before because it shares some property in common, and the the order of processing of component has changed leading to the other one being generated. (But that is a wider bug in the compiler outside of the scope of this refactoring)
