Positional focus: Switch focus from the currently focused node to another based on screen
position.
This launches a tree action that will find a candidate node and switch focus to it during
the next frame. Nodes that are the closest semantically (are in the same container node,
or overall close in the tree) will be chosen first; screen distance will be used when two
nodes have the same weight.
