* It does not work since Xcursor doesn't allow to attach
* any additional information to cursors in a retrievable
* way (there are comments, but no way to get at them
* short of searching for the actual cursor file).
* If this code ever gets used, the icon_window placement
* must be changed to recognize these placement options
* as well. Note that this code ignores info->hot_x/y.
