I agree.

I do think you should avoid creating different objects for different types 
of shapes.
Flake has a mechanism to create objects by passing a KoProperties object 
to the KoShapeFactory of your type.  The properties can state what kind 
of object it is.  A rect, a star or whatever you want.
The resulting shape will then be constructed with the proper vector paths 
already set and you can add a  
Enum VectoryType {Foo, Bar};  VectoryType &vectoryType(); 
on your shape so the tools and the saving method will be able to save 
things out as a specific type instead of a generic type.
