The accessor stacked-tree-width-ratio
accesses the width-ratio of stacked-tree, which is the ratio between the width of the root rectangle now and when the root was set.
The default action of the Ctrl-r
gesture is effectively the same as setting stacked-tree-width-ratio
to 1 and scrolling to the top left.
Note that width-ratio is not affected by changes in the width of the stacked-tree after the root has been set.
