Gets whether the window manager for this supports a certain hint from the <ulink url="http://standards.
freedesktop.org/wm-spec/wm-spec-latest.html">Extended Window Manager Hints specification</ulink> (EWMH).
When using this function, keep in mind that the window manager can change over time; so you should not use this function in a way that impacts persistent application state. A common bug is that your application can start up before the window manager does when the user logs in, and before the window manager starts net_wm_supports will return false for every property.
