f53964ead1 osd_regression regression now compiles. There was a first attempt at
getting the CPU backend converted.  Still not ready for prime-time by a long
shot.

06a05673da Refactored several testing utility functions into hbr_utils and vtr_utils where appropriate. Other tests will need to make use of these in the future.
Added cmp_utils as a place to put common testing utilities for comparing the results of hbr meshes vs. far/vtr results.

d0a624f373 Add "smooth UVs" to Far
- extend Far::PatchTables data structures & interfaces to store requisite
  information for channels of face-varying bi-cubic patches

4ced1b1461 Revised Level::VTags for semi-sharpness and added corner tag:
- added new tag for sharp corner, now used in isolation
    - split single semi-sharp tag in two for vertex and edge sharpness
    - updated tag propagation and all tests of previous semi-sharp tag
    - added clear() methods for all tags and simplified initialization

60a0fd783a Fix dxViewer build for latesst MSVC
- recent MSVC versions attempt to compile files with hlsl
  extensions when passed on the command-line. This breaks
  the build because these files are not meant to be compiled
  directly by MSVC. I removed the dependency from the
  CMakeList to prevent this from happening.
