This avoids a flickering when 2 windows are overlapping.

    window is destroyed (it is not enough i guess...)
  * utils/var_text.cpp: unregister the observer to the Stream variable
    in the destructor ! (fix a crash when changing skin)

  * x11_window.cpp: use XSetTransientForHint() to associate the windows
  to the "parent" window -> single window in the task bar

   text is updated (avoid many crashes)

  already been played (check the i_nb_played variable)
  * item.c: initialize i_nb_played to 0

  skins are not reentrant (at least with x11). Put commands in the queue
  instead.
  * commands/cmd_vars: commands to change variables
  * controls/ctrl_list.cpp: automatic scroll when the stream changes
  * src/bitmap.cpp: removed the scandinavian characters from the
    text font, they don't belong to ASCII (caused a stack corruption)

  (it helps a lot with wma).

   some methods.

   leading to invalid memory reads)

    - created a bool variable "playlist.isRandom" and 2 commands
    "playlist.setRandom(true)" and "playlist.setRandom(false)"
    - known bug: the playlist doesn't scroll automatically when the
    stream changes

 (text subs with mpg aren't working anymore unless using ps2)

Special thanks to Groniche and Google.

 * input: fixed "position" value as soon as possible after a see, this
way the intf doesn't show strange seek bar behavour.

introduced bugs).

* modules/gui/wxwindows/video.cpp: implement vout_ControlWindow().
* modules/video_output/directx/events.c, modules/video_output/x11/xcommon.c:
  + call vout_ControlWindow() when resizing in embedded mode.
  + implemented a VOUT_REPARENT/CLOSE mode in Control() so the interface can signal that it closes its video window.

 * mpgv: demux -> demux2.

demux2, and will be decreased as soon as demux -> demux2 is finished).

 implemented _only_ when it has a high precision.

implemented _only_ when it has a high precision.

worst until we completly switch to demux2...)
