5cb12805ca Added refinement and masks for Loop subdivision:
- added flag to Sdc MASK interface to interpret "face weights"
    - updated Catmark and Bilinear schemes to be aware of new MASK flag
    - added subdivision and limit masks for the Loop scheme
    - subclassed Vtr::Refinement into QuadRefinement and TriRefinement
    - updated tagging of components to be sensitive to applied scheme
    - fixed some quad assumptions in FVar refinement to support N-sided
    - internally generalized ::TopologyRefiner Interpolate() for <SCHEME>

dc27d303ac Reorganized/cleaned up Vtr::Refinement in preparation for adding tri-splitting:
- reorganized Refinement methods and pruned excessive comments
    - removed and added assertions related to Catmark scheme
    - added code to support alternate refined vertex ordering
    - updated FVarRefinement to be more independent of vertex ordering
    - updated Far::TopologyRefiner to fix face-varying ordering dependencies
    - fixed a few miscellanous compiler warnings

5ccd94c6d2 Reordered refined face-varying values so those for each vertex are sequential:
- added array accessors to properties of vertex values in vtr::FVarLevel
    - updated construction of base level face-varying topology
    - simplified population of face-varying properties in vtr::FVarRefinement
    - updated Far::TopologyRefiner::Interpolate/LimitFaceVarying() accordingly

69e6da8fab Fixed face-varying cases where the sharpness of values are inter-dependent:
- added ValueTag indicating sharpness dependency on another value
    - updated base level tagging to identify dependent semi-sharp values
    - updated refinement to consider dependency when reassessing semi-sharpness
    - updated interpolation to use dependent fractional weight when necessary

5f810a0f8e Add support for 'hole' faces
- adaptive mode: remove faces tagged as holes from the selection of faces to isolate

- uniform mode: faces tagged as holes are still included in the refinement process,
                however they are removed from patch tables

- future improvements: add a 'selective refinement' code path separate from 'uniform refinement'
  to handle this case without un-necessary subdivision work.

df23812759 Added proper fractional weighting for semi-sharp FVar boundaries:
- semi-sharp edges interior to FVar regions now properly recognized
    - added clear() method to FVar tags and reworked their initialization

c0907c7bc1 Introduces 'single-crease patch' : implements "Efficient Evaluation of Semi-Smooth Creases in
Catmull-Clark Subdivision Surfaces", Niessner et al, Eurographics 2012.

This change includes;
-topology identification for single-crease patch during adaptive refinement.
-patch array population (similar to boundary)
-sharpness buffer generation
-glsl shader

Eval stuffs will be coming.

4d84dfd7be Redefined face varying "boundary interpolation" to "linear interpolation":
- redefined and documented Sdc::Options::FVarLinearInterpolation
    - included "corners only" mode not possible with Hbr
    - updated usage within Vtr::FVarLevel

a79832b3a1 Far::PatchTables re-factor & clean-up
- remove Descriptor iterators
- switch 'unsigned int' indices to typed Far::Index

We aren't done yet... but its a step in the right direction

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

c399655dcc Landing 3.0.0.alpha
Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a

The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
