Description
  XGetWMSizeHints()  returns  the  size  hints	stored	in  the  specified  property  on  the  named  window.	If  the  property  is of type
  XA_WM_SIZE_HINTS, of format 32, and is long enough to contain either an old (pre-ICCCM) or new size hints structure, XGetWMSizeHints() sets
  the  various	fields	of  the  XSizeHints structure, sets the supplied_return argument to the list of fields that were supplied by the user
  (whether or not they contained defined values), and returns a non-zero status.  If the hint was not set, it returns a zero status.  To  get
  a window's normal size hints, you can use the XGetWMNormalHints() function instead.

  XGetWMSizeHints() supersedes XGetSizeHints().

  If  XGetWMSizeHints()  returns successfully and a pre-ICCCM size hints property is read, the supplied_return argument will contain the fol-
  lowing bits:

     (USPosition USSize PPosition PSize PMinSize PMaxSize PResizeInc PAspect)

  If the property is large enough to contain the base size and window gravity fields as well, the supplied argument  will  also  contain  the
  following bits:

     (PBaseSize PWinGravity)

  This function is used almost exclusively by window managers.
