    - split internal mask assignments into corner, crease and smooth cases
    - adapted all three schemes to the new structure
    - completed limit tangents for Loop
    - update TopologyRefiner Limit methods to pass newly required Rule

8da827336d Removes FarKernelBatch.
This is the first step to tease off Osd compute controller/contexts
from Far API.
Currently FarStencilTable only creates a kernelbatch for the entire range,
so we can use [0, numStencils) for all cases instead of KernelBatch.
This might not be true if we apply non-factorized level-wise stencils,
then we'll add another modular utility to serve those cases.

24f9dc154b Enable GregoryBasis patch.
PatchTablesFactory fills 20 indices topology into patchtable, and use it for eval and draw.

note: currently screen-space adaptive tessellation of gregory basis patches is
broken and cracks appear around them.

898d68ae79 Minor additions and revisions to TopologyRefiner interface:

    - removed ignored/unused "full topology" choice from AdaptiveOptions
    - added base face and vertex ordering logic to Refinement
    - addition of TopologyRefiner members for component counts and max valence

9222c9e169 Removed use of "full topology" flag with Far::AdaptiveOptions:

068ea4c7fa Face-varying fixes to support non-manifold features:
- updated original FVar inspection to deal witn non-manifold vertices
    - updated FVar refinement to handle > 2 faces per edge
    - couple of fixes to use parent topology when child not present

d38d683d0a Make sure to update the _maxEdgeFaces in the child from the parent
level before we do any further population from the parent as that may
further modify the child's _maxEdgeFaces.  When _maxEdgeFaces is incorrect
we may end up with stack corruption problems when
Far::TopologyRefiner::interpolateChildVertsFromEdges() goes to use this data
to allocate some stack space.
