-Add support for multulayerd meshes.
-Add an option to compute the laplacian on intrisic mesh.
-Add a mask to force computation of inpainted weights.
-Add the laplacian energy term.
-Improved peformance by getting the sparse matrix from the solve and then iterating over all (most zero) values.

Add IGeometrySelectionTransformer::PreviewRender() API, for rendering info during selection transforms. Currently being called by UGeometrySelectionManager::DebugRender() for active transforms.
FBasicDynamicMeshSelectionTransformer implements PreviewRender, draws selected mesh edges (tris as edges) and vertices, as well as affected edge ROI.
FDynamicMeshPolygroupTransformer overrides this behavior and draws polygroup edges/verts and edge ROI
FStaticMeshSelector and FVolumeSelector now create FDynamicMeshPolygroupTransformer for polygroup selections
FBasicDynamicMeshSelectionTransformer::bEnableSelectionTransformDrawing flag controls whether this edge drawing is enabled. Disabled on DynamicMeshComponent, enabled on StaticMesh and Volume.
Add Normals recomputation during tri and polygroup transforms in FBasicDynamicMeshSelectionTransformer and FDynamicMeshPolygroupTransformer
Add FGroupTopologyDeformer::EnumerateROIEdges() util function to support above

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
