Sets hints about the window management functions to make available
via buttons on the window frame.
On the X backend, this function sets the traditional Motif window
manager hint for this purpose. However, few window managers do
anything reliable or interesting with this hint. Many ignore it
entirely.
The @functions argument is the logical OR of values from the
#GdkWMFunction enumeration. If the bitmask includes #GDK_FUNC_ALL,
then the other bits indicate which functions to disable; if
it doesn’t include #GDK_FUNC_ALL, it indicates which functions to
enable.
