Now the usage of these variables is restricted to the case where `resetTransform` is set to `true`. Therefore, they can be left uninitialised here; a value is assigned before it's used in all the code paths as far as I can see.

It's just a small (premature) optimisation, it avoids creating two objects. I don't insist though.
