Exactly.  For a major "version 3.0" rewrite I'd want to start by 
defining a base canvas class with the drawing operations, and make sure 
all output formats supported those well.  Then one could imagine a 
multi-page subclass for those file formats where that makes sense, and 
the PDF one inheriting from this.
