- SEditorViewportClient now has an additional optional parameter in its constructor for the SEditorViewport that the client is attached to
- SBasePoseViewport, SDestructibleMeshEditorViewport, and SPhATPreviewViewport were all updated to inherit from SEditorViewport (previously just inherited from SCompoundWidget)
