I got a request to be more clear on animations:

"Clarification desirable?:
'If both the Œfrom¹ and Œto¹ transforms have the same number of transform
functions and corresponding functions in each transform list are of the
same type: ...'

Maybe we should define 'corresponding functions' more explicitly as
functions with the same index in the list?

I want to make sure that the following example is not covered by this case:
scale(...) translate(...) rotate(...)
translate(...) scale(...) rotate(...)"
