74f669b4c8 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.

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

deb924201c Stop MeshRegionGraph's small region merging algorithm from repeatedly merging regions that have already grown larger than the minimum region size. 
Fixes an issue where the Generate PolyGroups algorithm would randomly create very large, oddly-shaped regions in cases where the settings would normally generate many single-triangle regions.

ff0aaf7feb UVEditor: Implement functionality to allow the Seam tool to now remove seams, as well as add them. 
* Provides a mode selection for the Seam tool, switching between seam cutting mode and seam joining mode.
* Seam joining mode has an optional behavioral flag to have the path finding preferentially follow existing seams, making it easier to trace seam edges.
* DynamicMeshOverlay now supports merging elements, providing a method to merge one element to another, if they share the same parent, collapsing any references from the first element into references to the second.
* DynamicMeshUVEditor now supports removing seams from edges, providing a method to remove (via the new DynamicMeshOverlay functionality) seams from an edge collection by iteratively merging elements together.

8f2f94554c UVEditor: Performance tuning to improve runtime speed of rebuilding the UV overlays and meshes when edits or channel switches are performed. This significantly reduces the allocation and search churn when switching UV channels on high poly count meshes. 
This review duplicates and replaces the original review https://p4-swarm.epicgames.net/reviews/21689505 on //UE5/Main, primarily to bring it directly into 5.1 instead of robomerging from Main so close to the hardlock date. The issues discussed in the original review should now be addressed here.
