* modules/codec/ffmpeg/video.c: Better handling of aspect ratio change.

   use with #duplicate{}.

* Add some more comments on speaker layouts etc.

   fake access to create an efficient background image for the transcode
   module (avoids using the switcher module).

  adapted new "menu-palette" changes. This needs to be fixed by getting the CLUT.

   (default values borrowed from ffmpeg).

   changeset.

* modules/audio_output/directx.c: audio device selection based on a patch from Matthew Armsby (uberground at gmail dot com) + config option to disable float32 output.

* modules/stream_out/transcode.c: better picture heap leaking detection when encoding in multithreaded mode (needed if the encoder doesn't remove the pictures as fast as the decoder put them).

libvlc.c: Print --no-X in help to not confuse users. --noX and --no-X are still parsed and give the same results.

(closes #172)

mozilla devs should really fix bugs ...
