I'm amazed at the number of people arguing
"This is how the next one should be."
"No, this is how the current one is."
"But this is how the *next* one should be."
"Don't you understand this is how the current one *is*?"

It's only useless if you don't need it.

Nonesense. Once the tracing starts, you compute the final transformation 
matrix, just like you do now when there are multiple transforms.
