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 #rb none #preflight 63c047f4305002c64170f6a2 [CL 23667880 by ryan schmidt in ue5-main branch]
