+* Add a "real" text API in addition to the current "toy" API.
 
+* Implement text support for the image backend.
 
+* Add arc support.
 
+* Re-implement pattern support with a more PostScript-like API.
 
+* Virtualize the backend interface so that the various backends can be
+compiled conditionally.
 
+* Verification, profiling, optimization.
