Add support for inferring MaterialID, various methods for controlling creation of new polygroups in FOffsetMeshRegion
Add new PolyModelingFaceUtil.h/cpp with new function ComputeFaceSelectionFrame()
Add new PolyModelingMaterialUtil.h/cpp with new functions ComputeMaterialIDRange() and ComputeMaterialIDsForVertexPath()
Add Row/Column count accessor methods to FQuadGridPatch, and new function GetQuadOpeningAngle() that can return opening angle between two quad columns
Improve ComputeUVIslandForQuadPatch, now considers adjacent strips on either side to determine average target UV scale

Refactor core of FDynamicMeshEditor::DisconnectTriangles into an overload that takes precomputed triangle TSet and BoundaryLoops array, as some call sites already have computed this info
Refactor new-polygroup computation out of OffsetMeshRegion into UE::Geometry::ComputeNewGroupIDsAlongEdgeLoop util function in PolyEditingEdgeUtil.h/cpp
Add new function UE::Geometry::ComputeAverageUVScaleRatioAlongVertexPath in PolyEditingUVUtil.h/cpp
Introduce new type FQuadGridPatch, this is a book-keeping data structure for keeping track of "grid of quads" subregion of a triangle mesh, that provides easy access to vertex and quad/trainagle rows/columns
Add util functions ComputeNormalsForQuadPatch() and ComputeUVIslandForQuadPatch() in QuadGridPatchUtil.h
Add new version of OffsetMeshRegion geometric operation, inside FOffsetMeshRegion class. EVersion parameter determines which version of operation to run. Code for the "Legacy" version has not been modified, so back-compat is maintained. New implementation supports variable number of subdivisions along the Offset (via .NumSubdivisions), and computes normal/UV-islands "per group" in extrusion region, instead of per-quad. New version also splits bowties in extrude region before any additional processing, which simplifies some of the book-keeping/etc.
FExtrudeOp currently hardcoded to use use the FOffsetMeshRegion implementation

-Added a Blend function overload that handles barycentric interpolation of 3 skin weights.
-Refactored SetBoneWeightsFromBary (in DynamicVertexSkinWeightsAttribute.h) and ConstructVertexSkinWeightsAttribute (in SelectiveTessellate.cpp) functions to use the newly added Blend function for barycentric interpolation.
-Since the default Blend behavior has changed, make sure that unit tests in BoneWeightTests.cpp are refactored. Added more tests for cases when bBlendZeroInfluence is set to true and when using Blend for barycentric interpolation.

In some edge configurations two 'terminator' vertices (at the end of open bevel edge paths) are directly connected by a non-bevel edge that we will "open", and this creates a quad-shaped hole instead of a triangle-shaped hole (which was already handled). Detecting this case will arise is simpler before we change the topology, so it is done in BuildVertexSets(), stored in FBevelVertex::ConnectedBevelVertex, and used during mesh generation to call new AppendTerminatorVertexPairQuad function.
In BuildTerminatorVertex(), the search for a terminator split-edge may fail if the filtered triangle list ends up non-contiguous, preventing the vertex from being beveled (ie it is "stuck"). Code was added to both handle that case, and also try to force the list to stay contiguous.
