The same image goes to the built-in generator and to both imagor images, and status, dimensions, format, frames and alpha are compared. A generator that answers differently is held to that answer by a recorded override, so the test fails once the divergence disappears. It runs once per resize implementation, because make test builds the pure Go path while the images ship vips.
