-/* This isn't a "real" surface, but just something to be used by the
- * test suite to test a mythical backend that uses nothing but
- * fallbacks.
- *
- * The defining feature of this backend is that it has as many %NULL
- * backend function entries as possible. The ones that aren't %NULL are
- * simply those that must be implemented to have working fallbacks.
- * (Except for create_similar---fallbacks would work fine without
- * that---I implemented it here in order to create as many surfaces as
- * possible of type test_fallback_surface_t during the test suite
- * run).
- *
- * It's possible that this code might serve as a good starting point
- * for someone working on bringing up a new backend, starting with the
- * minimal all-fallbacks approach and working up gradually from
- * there.
