cdcec73088 Fixed Far::PrimvarRefiner::limitFVar prototype
Fixed the method signature of the internal limitFVar method to make
the dst argument a reference rather than a pointer to be more consistent
with earlier changes for other primvar classes. This also makes it
easier to use the public template LimitFaceVarying method to operate
on a wider range of primvar container types.

d6f68b17e8 Fix uninitialized stack memory used in topology refiner
The issue is that FeatureMask structure has size of an integer, but only
first 11 bytes are initialized, the rest is left non-initialized to a
stack memory of RefineAdaptive(). This will cause issues with IsEmpty()
which check whether any of integer's bits are set, effectively causing
jumps dependent on a non-initialized memory.

5e8e123d73 Major refactor of the construction of Far::PatchTable:
- new PatchTableBuilder class now implements PatchTableFactory::Create()
        - population of tables now independent of scheme or patch type
        - nested LocalPointHelper handles local point sharing and stencils
    - new PatchBuilder class encapsulates patch queries and conversions:
        - provides patch types associated with schemes and client options
        - handles all topological queries about patches in the base class
        - subclasses for the three subdivision schemes to support conversions
        - conversions encapsulated in new SparseMatrix class for re-use
    - removed Far end-cap factory classes and Far::GregoryBasis
    - extended adaptive refinement to support Bilinear scheme (not enabled)
    - extended Vtr::StackBuffer to avoid compiler inefficiencies

fe47db273c Fixed computation of PatchParam for tri refinement
Previously, Far::PatchTableFactory::computePatchParam() was
considering all faces with a face vertex count != 4 as
irregular.  This was incorrect for triangle refinement as
was the calculation of the UV subface parametric offsets for
triangle subfaces.

This is foundational work for implementing full support
for Loop scheme patch tables. This fix also allows correct
decoding of the parameter mapping for triangles resulting
from uniform refinement of Loop scheme meshes.
