/* This isn't a "real" surface, but just something to be used by the

 * test suite to help exercise the paginated-surface paths in cairo.

 *

 * The defining feature of this backend is that it uses a paginated

 * surface to record all operations, and then replays everything to an

 * image surface.

 *

 * It's possible that this code might serve as a good starting point

 * for someone working on bringing up a new paginated-surface-based

 * backend.
