909757ca9b Faster, simpler stencil table construction.
This is a new implementation of the stencil table construction algorithm found
in protoStencil.h. In local tests with production assets, the new algorithm is
~25% faster and significantly more stable, in terms of average performance

In one asset test, generating stencils for level 10 adaptive refinement of
BuzzLightyear was reduced from 18s to 13s.

392e5e8bed Remove #pragma once
While this may be worth revisiting, we should first quantify the benefits and
identify the compilers that support it. Ultimately, we may never use pragma
once in favor of strictly using standard C++.

74b78b3d17 Refactor again FarPatchTableFactory.
- rename "Regular end cap" to "BSplineBasis end cap"
- revert templating and add EndCapType into PatchTablesFactory::Options.
- make EndCapFactories internal in PatchTablesFactory.
- move end cap stencils into PatchTables, keep them relative to the max level.
- add a utility StencilTablesFactory::AppendEndCapStencilTables to splice and factorize endcap stencil tables.

43aa2500c4 Refactor far factories.
This change moves all gregory patch generation from Far::PatchTablesFactory
so that we can construct patch tables without stencil tables as well as client
can chose any end patch strategies (we have 3 options for now: legacy 2.x style
gregory patch, gregory basis patch and experimental regular patch approximation).

Also Far::EndCapGregoryBasisPatchFactory provides index mapping from patch index
to vtr face index, which can be used for single gregory patch evaluation on top
of refined points, without involving heavier stencil tables generation.

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.

d0a624f373 Add "smooth UVs" to Far
- extend Far::PatchTables data structures & interfaces to store requisite
  information for channels of face-varying bi-cubic patches
- implement gather function in Far::PatchTablesFactory to populate face-varying
  channels with adaptive patches
- extend accessor interface in Vtr::Level
- propagate code fall-out throughout OpenSubdiv code base, examples & tutorials
- extend vtrViewer code to visualize tessellated bi-cubic face-varying patches

abae4459e6 Adding support for gregory patches limit interpolation to Far::PatchTables
note: limit interpolation requires stencil-driven Gregory basis CVs

c237ab00fc WIP check-point for Gregory basis factorization
- adding support for StencilTables creation from a Gregory basis
- fix a bug in the prot-stencil allocator (slow memory pool was not being cleared properly)

17c682f055 WIP check-in for Gregory basis
Adding functionality to support the generation of stencils for the 20 CVs
basis of Gregory patches. This is still very rough... expect changes.
