e330b4513f Fix accumulation of stencil derivatives
- make sure not to skip CVs that have 0.0 weight because derivative may be contributing (non 0 tangent weight)

b27b55e4a8 Refactor Far::PatchTables
- split Far::PatchDescriptor into its own class (mirrors Far::PatchParam)
- hide PatchArray as a private internal structure
- add public accessors patterned after Far::TopologyRefiner (returning Vtr::Arrays)
- propagate new API to all dependent code

note: some direct table accessors have not been removed *yet* - see code for details

a9c32d6705 Add opensubdiv/version.cpp
This empty cpp file is added to address some cmake dependency resolution issues
with XCode project-based build generation.

I may add some functionality to version.cpp in the future

Thanks stopiccot for investigating the issue and doing most of the leg-work.

c2e8148efc Fix a Far::StencilTablesFactory crash bug on 'perfect' topology
Torii (and other planar topologies) are made entirely of regular b-spline patches and do not
generate sub-patches through adaptive isolation: we need to make sure that we construct
stencil tables with singular stencils for the coarse vertices instead of returning empty
tables (and crash in the limit stencils factory)

  feature along all the way through to Osd::Draw
