We already have "imprecise" polygons -- those which follow the basic rules 
but which have unspecified pixelization.  The idea of precise polygons is 
to build something which is guaranteed to generate the same result on all 
drawables, and which can be exactly reproduced on the client side.

If this requires specifying the computation method, then we'll go with 
that and leave algorithmic variation to the imprecise crowd.  Just as long 
as the specified algorithm generates reasonable results, follows the rules 
and is fast enough to avoid needing a software imprecise implementation.
