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

(this allows screen-aligned text to be attached more easily).
To mimic the old behavior, use ArrowItem.rotate() instead of the `angle` argument.

scientific notation (%g). This can be overridden by providing `format={value:g}` when
creating the parameter.
