// intelligently with other transform operations, so long as they represent the
// same decomposition. For example, if we have a transform that is made up of
// a rotation followed by skew, it can be blended intelligently with another
// transform made up of a rotation followed by a skew. Blending is possible if
// we have two dissimilar sets of transform operations, but the effect may not
// be what was intended. For more information, see the comments for the blend
// function below.
