  * Added SPU cropping.
  * Gnome interface segfault fix.
  * BeOS interface segfault fix by AnEvilYak (what's you real name btw?).

  Note: if you want to have a look at the currently buggy YUV subpictures,
        uncomment line 1999 of src/video_output/video_output.c. Don't report
        bugs about this, I _know_ it's a quick hack.

SPU renderer.
* Speed optimization in the handling of the unusual ephemer DVD subtitles.
