#===================#
HEAD
* Speed optimization in the handling of the unusual ephemer DVD subtitles.
* Little optimization to bozo's UnalignedShowBits fix.
* Race fix in the packet cache by Jon Lech Johansen <jon-vl@nanocrew.net>.
* Fixed a bug in UnalignedShowBits that makes some unaligned streams
not wotk correctly (for instance VLS' generated TS streams)
* Added support for some terribly braindead DVD subtitles in Kenshin
which do not have a "stop display" command. Anime fans rejoice!
* Fixed the BeOS interface to use p_aout_bank instead of p_main->p_aout.
* Coding-style butchery (mostly tabs).
* Changed the level arg in intf_WarnMsg so that it makes more sense.
* Beginning of the backport of Gnome to Gtk.
* Improved ac3 spdif output ( and made it work again :)).
* Added p_input->stream.p_selected_area->i_tell in input TS so that the
slider work with Transport Stream files.
* Moved b_fullscreen from p_vout->p_sys to p_vout and unified way of
toggling fullscreen.
* Tuned the Gnome interface appearance, added a Preferences window and
a Jump window, added Oct's playlist.
* Fixed a few warnings with gcc 3.0.
* aout and vout are now allocated in banks, making it possible to have
several of them at the same time.
