/* 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.
