It's part of the MWM hints, which are supported by nearly every window
manager today, and it's completely independent of Xlib, GTK+, etc. (i.e.
XCB will do as well). It's simply a property on the window.

Really, people, you should think of what you say. On the one hand you
complain that window managers are "bloated" and slow; and on the other
hand you request to add more unnecessary code to xfwm4.
