  XGetIconSizes - get preferred icon sizes.

Synopsis
  Status XGetIconSizes(display, w, size_list_return, count_return)
	Display *display;

  size_list_return
	   Returns a pointer to the size list.

  count_return
	   Returns the number of items in the size list.

Returns
  Zero on failure, non-zero on success.

Description
  XGetIconSizes()  reads  the XA_WM_ICON_SIZE property that should be set by the window manager to specify its desired icon sizes.  XGetIcon-
  Sizes() returns a Status of zero if a window manager has not set icon sizes, and a non-zero Status  otherwise.   This  function  should  be
  called  by  all programs to find out what icon sizes are preferred by the window manager.  The application should then use XSetWMHints() to
  supply the window manager with an icon pixmap or window in one of the supported sizes.  To free the data allocated in size_list_return, use
  XFree().

  For more information, see Volume One, Chapter 12, Interclient Communication.
