 'Transforms' are user-instantiated objects, which maintain state, handle all

 Conceptually, the API layering looks like this:
 
   [transform api]  (user interface)
-  [transform ops]  (per-type logic glue e.g. cipher.c, digest.c)
+  [transform ops]  (per-type logic glue e.g. cipher.c, compress.c)
   [algorithm api]  (for registering algorithms)
   
 The idea is to make the user interface and algorithm registration API
