Given the original text1, and an encoded string which describes the
operations required to transform text1 into text2, compute the full diff.
@param text1 Source string for the diff.
@param delta Delta text.
@return Array of DiffBase objects or null if invalid.
@throws IllegalArgumentException If invalid input.
