Barry Fowler a1c7be7c8e Addition of Bfr interface (1 of 4): opensubdiv/bfr
This set of commits includes the addition of a new evaluation interface
that treats a subdivision mesh more like a piecewise parametric surface
primitive.  The new interface was placed in namespace "Bfr" for "Base
Face Representation" as all concepts and classes relate to a single face
of the base mesh.
