missing, or an extra dock exists that is not mentioned in the restore state.
- #545: Allow more types to be mapped through Transform3D
- #548: Adds a disconnect() function that allows to conditionally disconnect signals,
including after reload.
Also, a SignalBlock class used to temporarily block a signal-slot pair
