Some transform-functions are not reifiable as a CSSTransformComponent, for example a matrix() with sibling-index() in it. In that case, rather than crashing, fall back to the basic CSSStyleValue reification. The crash doesn't happen yet, but would with the following commit's changes. Currently, Transformation::to_matrix() completely ignores unsupported argument types, but in the next commit that's replaced with TransformationStyleValue::to_matrix(), which attempts to handle them properly.
