Hi,
This patch adds notification on window restacking. Plugins may need to
do something when that happens. For example, it is used in the new
version of animation plugin to perform a fade effect when a window
moves above or below other windows (in the plugin's settings this
effect is selected as a focus effect, but it's actually a restack
effect).
Regards,
Erkin
