The snapshot's transform is provided to the pipeline. If the vertices are based on the coverage rectangle, then that will apply the snapshot's transform twice.

Fixes flutter/flutter#148213

I had not seen flutter/flutter#148213 before but coincidentally happened to notice something similar.

Verified that this will fix flutter/flutter#148213
