6353a138e5 GeometryProcessing: Improve the UV generation scheme PatchBuilder via a change to the polygroup generation stage, providing area aware sampling of the mesh surface and reducing the overcompensation effects that small, disconnected regions in the mesh were having on the overall segmentation. 
Also provides a new CVar, modeling.DisableAutoUVAreaDensitySampling, which when set, returns the behavior to the original algorithm, in case there are legacy reasons to maintain that behavior.

1d33bcc942 Add an option to the ChaosCloth TransferSkinWeights node that allows to choose the max number of bone influences per vertex. 
Propagate this change to the TransferBoneWeights and SmoothBoneWeights geometry operators by allowing to manually specify the max number of influences per bone for the output per-vertex weights.

08a4212d9b fix various issues with mesh bevel. Boundary-condition normals are now computed before any meshing. DisplaceVertices() now tries to keep terminator vertex positions on existing mesh edges (this should be improved to stay on group edges, in most cases a group edge can be selected topologically, but for now just snapping to mesh edges to handle the simple lowpoly-boxy cases). Simplify/improve computation of section planes in ApplyProfileShape_Round() - in all cases except corners, the section plane is well-defined by the two inset edge points and the original vertex position. This allowed removal of PlanarizeArcNormals function. Also now handling flipped orientation of quad patch relative to edge vertex sequence. 
Added more error handling inFQuadGridPatch::InitializeFromQuadPatch. Fixed property invalidating in PolyEdit bevel activity.

a86e132008 Add support for multi-segment bevels with optional round profile in MeshBevel. The new code path is completely separated from the previous code. Works OK but handling of valence-3 bevel corners (filled with a rounded triangle) could be improved. 
Expose in Geometry Script and PolyEdit functions.

d205e117bb GeometryProcessing: various utility functions to assist with rounded bevels implementation 
- add 2D version of VectorTanHalfAngle to VectorUtil.h
- add FDynamicMeshUVEditor::SetToPerVertexUVs, initializes overlay to have a single UV for each vertex
- add FQuadGridPatch::InitializeFromQuadPatch(), initializes the quad grid from external rows of quads and associated vertices
- add FQuadGridPatch::GetVertexColumn(), returns the list of vertices in a specific grid column
- add FQuadGridPatch::FindColumnIndex(), finds the index of the grid column that contains a specific Vertex ID

76c9580c1e Add support for transparent meshes/faces in detect exterior visibility algorithm + associated geometry script function. 
Also improve behavior (+ add control of behavior) for meshes with degenerate triangles, so meshes with degenerate triangles will not always be treated as visible.

5242b95c81 add an angle-based metric for controlling sphere approximation acceptance, and clarify that the existing radial tolerance is vs the best distance possible for an edge of that length rather than the actual distance to the sphere surface. The angle tolerance gives an intuitive control for how coarse a tessellation could be accepted as a sphere. 
Set a default value of 72 degrees max angle, so that e.g. cone volumes aren't recognized as spheres.

edc21b808e Add a normal-based clustering algorithm which groups connected triangle groups based on the current average normal of the group. 
Use this algorithm in the polygroups generator tool, so we get more useful groups on smooth surfaces (like a cylinder)

Also add a helper to the FSizedDisjointSet class to easily get the number of groups in the set and a mapping between compact group indices and sparse group IDs
