public bool set_static_gravities (bool use_static)
Warning: set_static_gravities is deprecated since "3.16".
Used to set the bit gravity of the given window to static, and flag it so all children get static subwindow gravity.
static gravities haven't worked on anything but X11 for a long time.
This is used if you are implementing scary features that involve deep knowledge of the windowing system. Don’t worry about it.
