99c34d2aec Adding functionality to store uniform face-varying data across multiple levels of subdivision
- switch FVarDataTable to a class
- add offsets to keep track of level
- modify dependent code
- rename 'totalFVarWidth' to 'fvarWidth'

d960990063 Remove FarMesh dependency from Osd*Context. The context constructor takes
subdivision tables and vertex edit tables directly.

44a7cb6a45 Refactor Far API.
* replace void* of all kernel applications with CONTEXT template parameter.
  It eliminates many static_casts from void* for both far and osd classes.
* move the big switch-cases of far default kernel launches out of Refine so
  that osd controllers can arbitrary mix default kernels and custom kernels.
* change FarKernelBatch::kernelType from enum to int, clients can add
  custom kernel types.
* remove a back-pointer to farmesh from subdivision table.
* untemplate all subdivision table classes and template their compute methods
  instead. Those methods take a typed vertex storage.
* remove an unused argument FarMesh from the constructor of subdivision
  table factories.

5aecc9e46e Fix Maya OsdPolySmooth node component output
The existing code in the node assumes that all the faces in the mesh have the same valence
when populating the component tables describing properties such as per-face material assignment.
This fix accounts for arbitrary topology.

fb3efcad71 Fix osdPolySmooth Maya plugin
- fix crash in the case of partial uv & color sets
- make sure that the default uv set is not dropped if its name is not 'map1'

note: the current fix carries the first uv set to the refined mesh, but custom
names are dropped and replaced by 'map1'. We appear to be running into a Maya
API bug.

b79ebd796c Fix UV merging in osdPolySmooth code example
Because our plugin sets UVs with individual face-varying vertices,
Maya interprets the buffer as discontinuous everywhere. Adding a
node in the graph that merges UVs along non-boundary edges resolves
this problem (until the plugin outputs the UV vertex indices in
an aggregated manner).

000cb400ca Revisit singular vertex fix for FarSubdivisionTables
The previous fix pointed far indexing tables to the origin vertex
of duped singular verts.

This fix goes one step further and actually shifts all vertex indexing
to start at the end of the coarse mesh vertices, using the space for
data that was previously occupied by duplicated singular verts.

The consequence is that client code no longer needs to duplicate vertex
data in vertex buffers (huzzah !).

- fix FarSubdivisionTablesFactory to shift factory vertex table offsets using Hbr's
  singular verts map
- fix schema table factories (Catmark, Loop...) to correctly use these offsets
- remove vertex data duplication code from osdPolySmooth example
- remove some (unrelated) cruft from glViewer example
- shape_utils unfortunately still needs to dubplicate the singular verts to
  allow the coarse edge drawing in our example viewers to work correctly
  (although it could be fixed to avoid data duplication too...)

c3cb17fa99 Modify Far remapping of singular vertices to point to their source vertex.
- Add a vector of index pairs to HbrMesh to track the index of a split
  vertex and its origin vertex
- Correct the Far remap tables in FarSubdivisionTablesFactory to point split
  vertices to their origin instead of themselves
- Fix regression/common/shape_utils.h to use the new HbrMesh::GetSplitVertices()
  method.
- Fix the osdPolySmooth example to use the new HbrMesh::GetSplitVertices()
  method.
- Add a paragraph to the documentation

c621c93aca Fix singular vertex handling by correctly populating the vertex buffer data.
Also:
- add logic to locate the GUI mel scripts where the binary is located, then default to script search paths
- remove min/max macro defines
- remove iso646.h header (covered by CMake build)
- remove redundant Osd includes
- remove some build warnings
- code style fixes
- build tweak: move the mel scripts to the correct location in the build area
