Syntax
UCLASS ()
class UDragAlignmentInteraction :
public UObject ,
public FDragAlignmentBase ,
public IModifierToggleBehaviorTarget

Interaction that can be added to (potentially multiple) UCombinedTransformGizmo object to allow them to snap to scene geometry in rotation and translation. Generally driven by an externally-provided UKeyAsModifierInputBehavior, or alternately can be directly updated by calling OnUpdateModifierState()
