- multiselection: bones can be multi-selected (using shift/ctrl) so that they can be bulk edited
- bones can be transformed individually (unlike in the level editor where the last selected element's transform is used as pivot)
- added USkeletalMeshGizmoContextObject to manage gizmo wrappers for skeletal mesh tools
- gizmo: re-used the transform gizmo work done with several fixes/improvements so that they can be used in other contexts
- UTransformGizmo can be used without TransformGizmoSource, most of the infos can be retrieved from the IToolsContextQueriesAPI
- UTransformGizmo can be passed an external StateTarget to handle transaction externally
- UTransformGizmo fixed rotations going in the wrong direction when dragging

- Warn about artifacts on meshes with open boundaries
- Fix some settings not being saved/restored
- Fix transaction name on undo/redo not matching the tool name
Also: Make the asset warning for base interactive tool only clear the tool's display message if it set a display message when it was last called, so that it is less likely to clear unrelated display messages when called with no warning to display.

- Added FTransformGizmoDataBinder which allows for gizmos to be bound to vectors such that the vectors are updated when the gizmo changes, and the gizmo is updated from vectors when asked. This should make it easy-ish to create displays of gizmos.
- Used the data binder in STransformGizmoNumericalUIOverlay, an overlay containing a draggable numerical UI panel for gizmos. Note that currently all changes, including typing, intentionally go down a gizmo drag path, meaning that they trigger the begin/end transform edit sequence calls, to make the tools treat them as a gizmo drag (in part because some tools might otherwise assume that a gizmo update is from an undo transaction or some other path that is special-cased).
- Added some slate things to ModelingEditorUI to support the numerical UI, in particular a viewport draggable box, and a widget that emits a tick delegate.
- Added some delegates to gizmo context object and combined transform gizmos to allow things to bind/unbind to/from them appropriately.

Add UInteractiveCommandResult, UInteractiveCommand::ExecuteCommand() now optionally can return a result subclass
Add UGeometrySelectionEditCommandResult, UGeometrySelectionEditCommand now can optionally return an "output" selection via this type
UGeometrySelectionManager::ExecuteSelectionCommand optionally can restore a selection after a command, via UGeometrySelectionEditCommandResult
Add UDisconnectGeometrySelectionCommand, implements disconnection of selected triangles (ie separates but not into a new mesh)
Add UModifyGeometrySelectionCommand, implements various selection edits (select all, expand to connected, invert, invert connected, expand, contract)
Add IGeometrySelector::InitializeSelectionFromPredicate() and ::UpdateSelectionFromSelection(), implement in UDynamicMeshSelector, used to implement selection edit commands
Add UI to enable new commands in Modeling Mode

- moved most functions defined in ParameterToTransformAdapters.h header into a new cpp to simplify debugging/etc
- UGizmoAxisTranslationParameterSource and UGizmoPlaneTranslationParameterSource now support optional constraints on the translation Delta
- CombinedTransformGizmo now has PositionAxisDeltaSnapFunction that, when in 'relative' mode, snaps the translation Deltas to increments via those constraints
- Added CombinedTransformGizmo::RelativeTranslationSnapping which controls relative vs absolute translation snapping, and can fetch value from ToolsContext
- Also added rotation-angle-delta constraint support UGizmoAxisRotationParameterSource and switched the gizmo to explicitly snap angle-deltas instead of trying to snap to "world rotation grid"
- Moved SnapToIncrement function to UE::Geometry namespace (in VectorUtil.h) and cleaned up a bit of duplicate code in UModelingSceneSnappingManager left over from pre-GeometryCore times
- Added FToolContextSnappingConfiguration::bEnableAbsoluteWorldSnapping, EdModeInteractiveToolsContext:: bEnableAbsoluteWorldSnapping and bits to hook this up
- Added UModelingToolsEditorModeSettings::bEnableAbsoluteWorldSnapping which stores this setting globally, but currently it is not serialized to config file, resets to default (Relative) on Editor restart
- Toolkit exposes toggle in the Selection toolbar menus

Add UE::ToolTarget::SupportsIncrementalMeshChanges() and ::ApplyIncrementalMeshEditChange(), these allow a Tool to directly edit a DynamicMeshComponent in the level (and emit corresponding MeshChange) so that a Tool can emit multiple undoable edits on a DynamicMesh
Add new USingleTargetWithSelectionTool base tool class, this is a USingleSelectionTool that can receive a FGeometrySelection. USingleTargetWithSelectionToolBuilder configures this type of Tool as necessary.
Add new LinearExtrusionOp dynamic mesh operator, provides linear-extrusion API to FOffsetMeshRegion using new Operator design (mesh shared via FSharedConstDynamicMesh3, CalculateResultInPlace() function to simplify direct usage in geometry script/etc)
Add new ExtrudeMeshSelectionTool, subclass of USingleTargetWithSelectionTool, exposes new LinearExtrusionOp, uses above ToolTarget functions to directly edit DynamicMeshComponent where possible
Enable new Tool in Modeling Mode
Add a few new functions to UMeshOpPreviewWithBackgroundCompute to simplify configuring InProgress and Secondary materials
Small additions to USingleSelectionTool

UModelingSelectionInteraction now supports concept of a "drag mode" that allows for drawing a marquee, brush-style interaction, etc. Added support for Marquee drawing but actual selection based on the marquee is not implemented yet.
ModelingToolsEditorMode now registers selector factories for Volumes and Static Meshes. Creating selectors for these types is dynamically configurable via new UProperties.
Added mesh-selection-specific UPathSelectionInteraction which provides a simple continuous-select-while-dragging interaction
Added a viewport overlay toolbar for mesh selection, supports changing selection mode, drag mode, selectable object types.
Viewport overlay toolbar also exposes a "quick settings" flyout for changing various modeling mode settings
Added URectangleMarqueeInteraction which is a simplified variant of URectangleMarqueeMechanic that does not require a Tool and doesn't create it's own InputBehavior
USingleClickOrDragInputBehavior now supports changing Drag target
Added a few placeholder icons

* 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.
