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.
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.
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.
