This change restores the use of 4-bits in Far::PatchParam to
encode the refinement level of a patch. This restores one bit
that was stolen to allow for more general encoding of boundary
edge and transition edge masks. In order to accommodate all
of the bits that are required, the transition edge mask bits
are now stored along with the faceId bits.
Also, accessors are now exposed directly as members of Far::PatchParam
and the internal bitfield class is no longer directly exposed.
- changes completely deprecate AddWithWeight(T, float, float, float)
- added new EvaluateBasis() method to PatchTables
- replaced usage of old Evaluate...<T,U>() methods with EvaluateBasis()
- removed old Evaluate...<T,U>() methods
- removed now unused Interpolate...<T,U>() functions in far/interpolate.h
- moved low-level basis code from far/interpolate.* to patchBasis.*
