  90  * placement.  This information is gathered at various places: the (re)capture
  91  * code, AddToWindow(), HandleMapRequestRaised(), ewmh_events.c and others.
  92  *
  93  * initial_state
  94  *   The initial window state.  By default it carries the value DontCareState.
  95  *   Other states can be set if
  96  *    - an icon is recaptured or restarted with session management
  97  *    - the StartIconic style is set
  98  *    - GNOME, EWMH, foobar hints demand that the icon starts iconic
  99  *   The final value is calculated in HandleMapRequestRaised().
 100  *
 101  * do_override_ppos
 102  *   This flag is used in PlaceWindow().  If it is set, the position requested
 103  *   by the program is ignored unconditionally.  This is used during the
 104  *   initial capture and later recapture operations.
 105  *
 106  * is_iconified_by_parent
 107  *   Preserves the information if the window is a transient window that was
 108  *   iconified along with its transientfor window.  Set when the window is
 109  *   recaptured and used in HandleMapRequestRaised() to set the according
 110  *   window state flag.  Deleted afterwards.
 111  *
 112  * is_menu
 113  *   Set in menus.c or in the recapture code if the new window is a tear off
 114  *   menu.  Such windows get special treatment in AddWindow() and events.c.
 115  *
 116  * is_recapture
 117  *   Set for the initial capture and later recaptures.
 118  *
 119  * default_icon_x/y
 120  *   The icon position that was requested by the application in the icon
 121  *   position hint.  May be overridden by a style (0/0 then).  Set in
 122  *   HandleMapRequestRaised() and used in the icon placement code.
 123  *
 124  * initial_icon_x/y
 125  *   The icon position that is forced during a restart with SM.  If set it
 126  *   overrides all other methods of icon placement.  Set by session.c and used
 127  *   in the icon placement code.
 128  *
 129  * use_initial_icon_xy
 130  *   If set, the initial_icon_x/y values are used.  Other wise they are
 131  *   ignored.
