Early pass: Identify top-three FX layers (update in Merge Animation if in replace mode)

• Merge Animation replace mode needs to be careful not to break RC! (TODO) Late running pass: Inject layer 0: Animate _MMD_NotActive to 1 If layers 1/2 are not part of the original FX: Insert dummy layers (empty motion) Add layer (can this be a dummy layer?):
• If _MMD_NotActive is 0, drive the original 3 layers off (and back on when 1) Opt-in: New state machine behavior to control MMD behavior (opt in or opt out)
