d1b9e45c13 Fixed potential crash in Far::StencilTableFactory 
Now StencilTableFactory::AppendLocalPointStencilTable() does
nothing when the localPointStencilTable is empty. This avoids
a potential crash (failed assertion) when both the baseStencilTable
and the localPointStencilTable are empty, as is the case for
simple geometry like the all-quads torus regression test shape.

c588e95e13 Disabled fractional spacing w/o screen space tess 
For now, the common patch shader code supports fractional spacing
modes only when screen-space tessellation is also enabled.

It's possible to relax this restriction, but that requires changing
the client shader interface.

b0d612f837 Restored support for fractional tessellation 
This change includes support for both fractional_even_spacing
and fractional_odd_spacing.

The implementation follows the existing pattern of re-parameterizing
the tessellation domain only along transition boundary edges. This
allows for crack-free tessellation, but it might be better to
consistently re-parameterize all of the outer edges of all patches,
which also would be required for numerically watertight tessellation.

This is implemented in a way that requires no changes to the client
shader API. It should be more efficient to move some computations to
the control/hull shaders and reduce divergence in the execution of
eval/domain shaders.

024da1f729 Reduce the transient memory consumption in endcap construction. 
- instead of accumulating GregoryBasis::Point (fixed size stencils
  backed by stackbuffer), pack the stencils into StencilTable as they
  are evaluated
- use single integer for varying stencils of patch points, not
  a GregoryBasis::Point
- cap the reserved stencil entry size.

fb4f3f6a62 Merge pull request #741 from takahito-tejima/bspline 
optimize PatchTableFactory::Create performance

The primary hesitation here is that this change alters the approximation for BSpline end caps, however the consensus is that BSpline end caps were already the most extreme approximation, so it makes sense to sacrifice quality for speed.

0e91dcd177 Optimize gregory basis endcap generation. 
- replace std::vector with vtr::StackBuffer in GregoryBasis::Point
- remote getQuadOffsets call from ProtoBasis
- rewrite some inefficient code in the endcap generation.

Note that this is a temporary remedy for the performance issue in 3.0.
We'll fix it again in the later release.
