ff1adaf1b4 GeometryProcessing: fix handling of single-edge case in MeshBevel. Need to properly compute Wedge border edge information so that the edge-pairs can later be found and added to the edge-correspondence map.

0e961a1e23 ModelingTools: add Edge Bevel operation in PolyEdit Tool. New UPolyEditBevelEdgeActivity, and operations to initialize it in PolyEdit. This bevel operation currently uses an explicit bevel-distance rather than a live viewport interaction, and as a result required adding a separate 'apply' button inside the PolyEditTool panel (via new UEditMeshPolygonsToolAcceptCancelAction). The UX here is terrible but it's not clear we can do better in 5.0 timeframe. 
GeometryProcessing: add support for beveling the border ring(s) of a triangle or polygroup-face selection. Improve polygroup assignment around bevel loops, previously the entire loop received a single polygroup which is not what the user expects in polygroup-modeling. Now a new polygroup is assigned for each unique group-edge-pair. Terminator vertices now also generate a new polygroup if there are 2 or more adjacent groups, previously behavior (assigning to arbitrary nbr) was not useful during polygroup-edting.

7bd74ffee4 GeometryProcessing: add basic UV calculation and materialID support to MeshBevel. Add PolyEditingUVUtil file for UV computation utility functions in Poly-editing. Currently only ComputeArbitraryTrianglePatchUVs() function which uses expmap to compute UVs and (approximately) scales UVs to match UV scale on surrounding border triangles. 
GeometryScript: add ApplyMeshPolygroupBevel operation

8c5b55b152 GeometryProcessing: Refactor edge-loop inset calculation code from InsetMeshRegion into new utility functions in PolyEditingEdgeUtil.h. Use in FMeshBevel::DisplaceVertices() to improve edge insetting. Also add FMeshBevel::FixUpUnlinkedBevelEdges(), to repair vertex and edge ID lsits in unlinked open-span edges after unlinking vertices.

ee57dd4ec7 Update TriangulateSimplePolygon to by-default orient its output triangles in the most-often-desired orientation (w/ triangle winding the opposite of the polygon winding, for example this is desirable when the polygon is generated from boundary edges on a hole to be filled) 
Add test coverage for polygon triangulation functions to ensure they create triangulations with the expected orientations

cea638d0b0 GeometryProcessing: add initial MeshBevel operation. Still a WIP, does not handle UVs at all, or interior-region vertices, and the current solve for vertex positions produces horrible-looking bevels, but the main topological problems seem to be solved. 
Various utility functions added to MeshIndexUtil.h and FIndex2i/3i.
