* Reversed index buffers are used to handle negative scaling transforms. Since HLOD meshes will never be used with such transforms, we can get rid of these buffers and reduce memory usage.

a FGetMeshParameters parameter is now used to request a specific LOD, as well as the option of requesting tangents
this will also allow further customization in the future, if required, by adding attributes to the FGetMeshParameters struct

-Added a convenience function for getting an array of bone names from a reference skeleton.
-Added MeshBones.h/cpp that contain utility functions to deal with dynamic mesh bone attributes

Add DynamicMeshSelector::UpdateAfterGeometryEdit API. StaticMeshSelector implementation updates static mesh after an Edit instead of emitting MeshChange on temporary DynamicMesh.
Delete and Retriangulate Commands now use this API instead of directly emitting transaction, so now these commands work properly on Static Meshes.
FStaticMeshComponentSelectorFactory::CanBuildForTarget now only allows UStaticMeshComponent specifically, filtering out subclasses. This is not ideal but I don't know what else we can do for now, there are many subclasses like ISMC, SplineMeshComponent, etc, that will not work w/ the Selection system. Also now filtering out Engine assets and cooked assets.
ModelingToolsEditorMode now listens for blueprint pre-compiles, and when this occurs, clears the active selection and selection targets. This is necessary because if the selection Component was part of a BP, on recompile it is re-instanced and the old pointer goes stale. Possibly can handle this better or at a more granular level, but clearing the selection is safest. This currently results in things not being undoable because the FChange transactions are on the "old" UDynamicMesh that no longer exists.
UModelingToolsEditorMode::UpdateSelectionManagerOnEditorSelectionChange now does a more thorough job of inspecting the current Actor/Component selection to find Components that could work w/ the selection system.

- Factor out "extra corner" finding code from PolyEd and add support for it in subdivide tool.
- Add support for rounded corners for mesh boundaries.
- Override subdivision scheme during tool usage rather than just at tool start, to allow extra corners to fix some issues.
- Add some clarifying comments about schemes.

- Fix conversion sometimes making degenerate tris and firing an ensure.
- Fix volume conversion sometimes creating cracks in volumes when dealing with non-convex faces (by deleting necessary colinear verts)
- Make simplification preserve group boundaries when asked.
- Remove colinear verts along group boundaries without losing boundaries when preserving groups.
- Break up faces that have holes into convexes rather than emitting per-triangle faces.
- Make mesh to volume tool use same path for conversion as tool targets, and add controls for preserving groups and simplifying
- Revert to ear clipping if delaunay triangulation fails in converting back from volume

Added a CreateNewActor function to EditorModelingObjectsCreationAPI which finds a factory capable of producing actors of the same type as a provided template actor to create the new actor without needing to create entirely new assets as would have been necessary with the existing functions in EditorModelingObjectsCreationAPI.

Selection enable/disable can now be toggled dynamically via mode settings popup, toolbar will hide/show based on current setting state.
GeometrySelectionManager is now always created. New Mode function GetMeshElementSelectionSystemEnabled() indicates whether selection is currently enabled, when disabled active targets will not be tracked.
Selection Toolbar icons now are disabled while in a Tool (as selection system is not active then)
New Static Mesh Assets and Volumes created using Modeling Tools now default to unlocked, via new functions on StaticMeshSelector / Volume Selector.
Unlocked Asset/Volume sets are cleared on level change
Added cvars modeling.Selection.EnableStaticMeshLocking and modeling.Selection.EnableVolumeLocking which can be used to fully disable lock-ability of StaticMesh/Volume (default true)
shortened some names of tool group tabs, as labels are now shown and long names make the bar wider
Added a few toast notifications for when setting state changes require a mode or editor restart.

Add IGeometrySelectionTransformer::PreviewRender() API, for rendering info during selection transforms. Currently being called by UGeometrySelectionManager::DebugRender() for active transforms.
FBasicDynamicMeshSelectionTransformer implements PreviewRender, draws selected mesh edges (tris as edges) and vertices, as well as affected edge ROI.
FDynamicMeshPolygroupTransformer overrides this behavior and draws polygroup edges/verts and edge ROI
FStaticMeshSelector and FVolumeSelector now create FDynamicMeshPolygroupTransformer for polygroup selections
FBasicDynamicMeshSelectionTransformer::bEnableSelectionTransformDrawing flag controls whether this edge drawing is enabled. Disabled on DynamicMeshComponent, enabled on StaticMesh and Volume.
Add Normals recomputation during tri and polygroup transforms in FBasicDynamicMeshSelectionTransformer and FDynamicMeshPolygroupTransformer
Add FGroupTopologyDeformer::EnumerateROIEdges() util function to support above
