5b2cbccdaf 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.

5c8db45f2c fix bug where clipper ellipse could request more than max_int steps for an ellipse and crash 
+ make the one place that calls that ellipse method use its own logic to specify the number of steps per radian, so it will request many fewer steps per ellipse

2c11bfc349 Mesh Bevel: remove ensures that are getting hit in some cases in Lyra. Failure is not catastrophic, so we do not really need to ensure here.

687489972d Make SimpleShapeSet3's sphere transform method match the editor's approach for transforming simple collision spheres -- scaling the radius by the minimum abs-value axis scale -- to get more consistent results when baking component transforms.

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

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.
