f706062ab1 Added support for semi-sharp features along face-varying boundaries: 
- added semi-sharp tag to FVar ValueTags and applied in base FVarLevel
    - re-assess status of tagged semi-sharp values in each FVarRefinement
    - detect and apply fractional weighting in InterpolateFaceVarying()

34f397c52b Checking in work-in-progress on face-varying boundary interpolation: 
- added more recognition of Hbr behavior
    - refactored smooth boundaries to identify continuous spans
    - mark spans as sharp corners if interrupted by internal dart edge

0d4582b34c Add 'sticles' to the glEvalLimit code example 
Make the sample locations dynamic by adding a velocity vector. Face boundary
crossing is handled using the new ptex adjacency functionality recently
added to the Far::TopologyRefiner.

09789296d9 Modified weighting of sharpness values for Chaikin crease method: 
- semi-sharp edges prevented from decreasing by averaging with inf-sharp
    - averaging now includes only semi-sharp edges around the vertex
    - see regression/shapes/catmark_chaikin2

  coarse control vertices
- refactored interpolation code out into Far::PatchTables
- corrected tangent interpolation

4dd366593d WIP FarLimitStencilsFactory 
- bi-cubic patches should be mostly covered, although portions of the interpolation code
  need to be refactored out into Far::PatchTables as vertex templated functions (following
  patterns established in the Far::TopologyRefiner)

- end-cap patches still have to be done (prob. going to drop Gregory in favor of bilinear)

- Presto needs a fully bilinear code path (no patches) - really ???
