CSSTransformComponents hold other CSSStyleValues as their parameters. We want to be able to create internal representations from those parameters without them caring if they would be valid when directly assigned to the property. This is a temporary solution to make transform functions work. To be completely correct, we need to know what is allowed in that context, along with value ranges - a combination of the contexts we create when parsing, and when computing calculations. For transform functions, this doesn't matter, as there's no limit to the range of allowed values.
