import Quickshell The TransformWatcher monitors all properties that affect the geometry of two Items relative to eachother.
NOTE
The algorithm responsible for determining the relationship
between a and b is biased towards a being a parent of b,
or a being closer to the common parent of a and b than b.
Known common parent of both a and b. Defaults to null.
This property can be used to optimize the algorithm that figures out
the relationship between a and b. Setting it to something that is not
a common parent of both a and b will prevent the path from being determined
correctly, and setting it to null will disable the optimization.
This property is updated whenever the geometry of any item in the path from a to b changes.
Its value is undefined, and is intended to trigger an expression update.
