fc967a2d79 Add structured down-sampling options to custom voronoi point sets, to allow less-clumped / sharp-edge-favoring down-sampled point sets from meshes and bones
Add a FPriorityOrderPoints class to help with downsampling, implementing a similar algorithm to what is used by physics to help choose collision sample points as a subset of mesh vertices but more generally accessible

633ca0f90d fix geometryprocessing tests by changing MeshAABBTree3 to have the original 'effective' default tris per leaf (of 3), rather than the original value of 4, now that the off-by-one bug in how it handles that value has been fixed.

1e25b7bd06 Add WriteOBJ function for FDynamicMeshAABBTree3 and ReadOBJ function useful to inline small obj files
Also do some refactoring to pass settings structs which improve readability when setting options, reduce the need to change call sites due to signature changes, and allow overloading of Read/Load functions which return some type

1b53940a8c GeometryCore: Add Embedded Path Tracing across FDynamicMesh surfaces and Intrinsic Triangulations of FDynamicMeshes. Also update Mesh Laplacian Code to generate Cotan Laplacians from Intrinsic Triangulation.
MeshGeodesicSurfaceTracer.{h,cpp}  -  Add embedded path tracing.
GeodesicSurfaceTracerTests.cpp     -  unit tests for embedded path tracing

IntrinsicTriangulationMesh.{h, cpp}  - Adds two Intrinsic Triangulation mesh types (the more sophisticaed requires embedded path tracing)
IntrinsicMeshTests.cpp               -  unit tests for Intrinsic mesh types.

MeshLaplacian.{h,cpp}                - Adds new enum types for Intrinsic Delaunay Triangulation (IDT)  Laplacians
LaplacianOperators.{h,cpp}           - Adds wrappers and allow enum switches to build IDT Laplacians if requested
LaplacianMatrixAssembly.h            - Actually construction of IDT Laplacian.
Laplacian.cpp                        - Added trivial unit test for construction of IDT Laplacian

4e422005cd GeometryCore: Add minimal UE::Math::TVector2<T> implementation and FVector2f/2d typedefs locally in GeometryCore VectorTypes.h. Replace existing FVector2<T> with this class, in preparation for LWC conversion. FVector2 members ::Distance() and ::DistanceSquared() moved to free functions. Update all call sites and references to FVector2.

e3183cb1e7 GeometryProcessing: clean up mesh timestamps.
- remove FDynamicMesh3::Timestamp (unused), rename Shape/Topology Timestamps to Shape/TopologyChangeStamp, change to atomic<uint32>
- add FDynamicMesh3::bEnableShapeChangeStamp, default to false, to disable ShapeChange tracking. Add ::SetShapeChangeStampEnabled() and ::HasShapeChangeStampEnabled() to configure.
- replace FDynamicMesh3::UpdateTimestamps() with UpdateChangeStamps()
- add bTrackChange param to FDynamicMesh3::SetVertex(), optionally updates ShapeChangeStamp (if enabled). Default true. Remove SetVertex_NoTimeStampUpdate(), update call sites.
- add FDynamicMesh3::GetChangeStamp(), returns combination of Shape and Topology stamps as uint64
- rename TTriangleMeshAdapter::GetTimestamp() to GetChangeStamp(), update usages
- remove TPointSetAdapter::Timestamp()   (was not used in code)
- update TMeshAABBTree3 to use GetChangeStamp(), update internal checks to call IsValid() instead
- update TFastWindingTree w/ similar changes
- update calls in UVEditor, may require further updates
