- corrected stencil estimates according to the interpolation mode
- removed the added error checking for the tables provided
- use uniform vertex patches when varying interpolation specified
- added internal option to generate polygons vs patches when uniform
- updated PatchTableFactory to identify patches at a specified level

This updates the patch basis evaluation functions in Osd
to match recent changes to far/patchBasis.
This also exposes a common facility for dealing with PatchCoord,
PatchArray, and PatchParam. These are exposed as global functions
operating on struct data, since C++ style class methods are not
supported by all of the Osd shader and kernel execution envirionments.
Changes:
- Merged far/patchBasis.cpp to osd/patchBasisCommon{,Types,Eval}.h
- Exposed PatchCoord, PatchArray, and PatchParam to Osd kernels
- exposed OsdEvaluatePatchBasis and OsdEvaluatePatchBasisNormalized
- Updated CPU, TBB, Omp, CUDA, OpenCL, GLSL, HLSL, and Metal evaluators
- Updated glFVarViewer
- identify the subrange of originating patch faces while assigning handles
- limit queries and memory allocation to the identified subrange of faces
- separate quadtree construction for quad and triangular patches
- added new PatchTable member to indicate uniform (linear) construction
- initialize new member in PatchTableFactory
- use new member to determine result of IsFeatureAdaptive() query
- added new TopologyRefiner member to detect presence of irregular faces
- added new Vtr::Level::VTag to indicate vertex incident an irregular face
- populated new VTag bit when irregular faces present
- updated refinement to clear new bit for refined faces
- branch adaptive refinement in linear cases to avoid testing features
- updated feature detection for irregular faces -- now a simple bit test
- updated PatchBuilder with now-trivial test for incident irregular faces
- individual basis functions now purely normalized with no PatchParam
- two new higher level functions deal with patch type and PatchParam
- updated Far::PatchTable and Osd evaluators that used old methods
- clarified handling of isolated/unisolated features in IsPatchRegular()
- simplified GetPatchBoundaryMask() to make use of bit masks
- removed private method supporting approx-smooth-corner-as-sharp option
- removed debugging tests verifying irregular patch points
- Far::PatchBuilder additions to identify spans around non-manifold corners
- re-organized patch regularity test to inspect individual corner features
- updated partial span gathering function to handle non-manifold cases
- ensure vertex tag xordinary bit remains unset when non-manifold
- added necessary options to struct LimitStencilTableFactory...::Options
- updated Create() to support creation of varying and face-varying stencils
- updated Create() to provide clarity and stricter compatibility checks for
the optional StencilTable and PatchTable arguments
- modified Doxygen comments for Create() to clarify requirements of the
optional table arguments
- added missing StencilTableFactory::AppendLocalPointStencilTableVarying()
- changed UpdateValues() use of *T to &T for consistency with PrimvarRefiner
- assigned unique types <T> and <U> to src and dst arguments for consistency
- kept the *T interfaces for backward compatibility
- extended patch construction in base PatchBuilder to support triangles
- added extraction of regular triangular patches to base PatchBuilder
- converted irregular patches to supported patch types in LoopPatchBuilder
- fixed missing PatchDescriptor functionality for Loop triangle
- add new PatchDescriptor::Type for Gregory triangle
- extended PatchParam boundary mask from 4 to 5 bits (!)
- added new PatchParam methods for parameterization of triangles

- replaced pointer aliasing in bitwise combinations with use of new methods
- assigned appropriate patch count and base offsets to varying arrays
- assigned appropriate patch count and base offsets to face-varying arrays
- fixed append to face-varying PatchParam buffer for each array
- extended Far::PatchTable's FVar channels with two descriptors and stride
- updated Far::PatchTableFactory to properly construct FVar patch arrays
- extended Osd::PatchArray with two descriptors and common stride
- updated Osd::CpuPatchTable and CpuEvaluator to use PatchArray extensions
- reverted original methods to operate in single precision instead of both
- removed overloads in favor of direct stencil table access and update
- updated precision related assertions with clearer condition
- updated far/tutorial_6 to use template stencil table access
- updated far/tutorial_9 to use conventional stencil table access
- replaced use of Append() with Assign(index) now that row size is clear
- added asserts for all row sizes to ensure assignment matches allocation
- simplified utility class for SparseMatrix point/row down to bare minimum
- overloaded PatchTableFactory::Create() to take subset of base faces
- overloaded TopologyRefiner::RefineAdaptive() to take subset of base faces
