  if this breaks the linux or win32 mozilla plugin then it should be restored.

The playlist works fine again (with ASCII/Latin locale charset).
When in UTF8, it might be a good idea to check for invalid bytes
sequences and replace them with question mark - at the moment
wxWidgets still leave the whole text blank which result in blank
playlist item in the playlist.

(the documentation for wxWidgets 2.5.3 is wrong :
 wxConvCurrent (which does not work) does not point
 to wxConvLibc nor wxConvLocal (which both work))

It is now possible to use wxvlc with non UTF-8 locale.
Previously, any text item with non-ASCII character in it would be
blank.

* modules/stream_out/transcode.c: fixed segfault.

* include/vlc_filter.h, vlc_video.h, src/video_output/vout_subpictures.c: new simpler and more powerful text renderer api.
* modules/misc/freetype.c: rewrite to the new api + outputs YUVP subpicture regions now.

* Fix udp->tcp rollover when using multicast in rtsp. now bail after 36 seconds in case of multicast, .9 seconds otherwise. Bail after 3secs of no longer receiving data (multicast or unicast).

* dirty patch to tell vlc (on osx) that it needs -liconv when it links to libcdio. This should be fixed in the libcdio pkgconfig, but i'm tired of figuring out how to patch libcdio to do this.

   doing something

- Some cleanup

  reuses a given picture_t without allocating a new one.
* modules/video_output/picture.c: New --picture-height and width options
  to do the scaling in the vout thread. Misc bug corrections.
* modules/video_filter/mosaic.c: Less overhead.
* modules/codec/ffmpeg/video_filter.c: Do the scaling before the conversion
  in case the original size is bigger than the destination.

* modules/codec/ffmpeg/video.c: assume (M)JPEG YUV420 is the same as I420 (we could convert to have the exact chroma but that would be slower).
