The Transformation class wasn't really accomplishing anything. It still had to store StyleValues, so it was basically the same as TransformationStyleValue, with extra steps to convert from one to the other. So... let's just use TransformationStyleValue instead! Apart from moving code around, the behavior has changed a bit. We now actually acknowledge unresolvable parameters and return an error when we try to produce a matrix from them. Previously we just skipped over them, which was pretty wrong. This gets us an extra pass in the typed-om test. We also get some slightly different results with our transform serialization, because we're not converting to CSSPixels and back.
