UMeshElementsVisualizer::SetMeshAccessFunction() now takes a TFunction with a TFunctionRef argument, instead of with a FDynamicMesh3* argument. This allows the UMeshElementsVisualizer to access the target mesh via the ProcessMesh()-style call on a UPreviewMesh, UDynamicMesh, etc, rather than receiving direct pointer access. See UWeldMeshEdgesTool::Setup() for example usage.
Add UMeshOpPreviewWithBackgroundCompute::ProcessCurrentMesh(), which forwards to the embedded UPreviewMesh::ProcessMesh() (which can be used with the above)
Add UE::ToolTarget::GetMeshDescriptionCopy() to ModelingToolTargetUtil, similar to existing DynamicMesh variant that will auto-compute tangents if necessary.

Add UMeshWireframeComponent, this is a component that renders mesh edges as lines, with line color/thickness varying depending on line type. Accesses mesh via an API so client does not have to handle iterations/etc (derived from LineSetComponent).
Add UMeshElementsVisualizer, subclass of UPreviewGeometry that displays mesh information (currently using UMeshWireframeComponent)
Small optimization to ULineSetComponent to avoid calling MarkRenderStateDirty() for each line when adding many lines.
