27/08/09:
  - Added overwrite of profile and level of AVC streams when adding tracks in mp4box(from ISOFF or .264). Use ":profile=X" and ":level=Z" when importing
  - Fixed chapters and text tracks handling for iTunes. Using the -ipd option in MP4Box should fix all subtitles tracks.
    When adding a track (including subtitle), it is now possible to override the track layout. For example:
      MP4Box -add test.srt:layout=0x20x0x-1 test.mp4
     will set the track box to be max width of the file tracks, 20 pixels height, translated by 0 pixels left and aligned to the bottom (max height - 20)
    To add a chapter track, you simply have to add ":chap" in the -add command. 
  - Added modular compilation of most libgpac features. See configure or include/gpac/configuration
  - Fixed streaming interoperability with Live555 
  - More fixed and speed improvement in VRML/BIFS scripting

  - Support for MediaAccessEvent (spec still under development ??)
  - Added support for user extensions (global class only) in JS through modules - cf gpac_js for sample code.
  - Initial support for 3GPP DIMS (file creation and dumping + playback)
      * Currently only SVG as overlay is supported for DIMS files, we are not sure about the specification on this topic
      * RTP hinting /playback is not supported yet      
  - Support for SVG foreignObject - all GPAC supported content can be played in a foreign object
  - Added automatic switch between 2D and 3D context for VRML/BIFS Inline node 
  - Basic support for DCCI queries: 
    * the DCCI object is exposed in scripts as 'DCCIRoot'
    * the related document can be specified in GPAC configuration file in the [General] section with the 'EnvironmentFile' key 
      pointing to an XML file to use as the ontology context
    * DCCI's propertyFilters are NOT supported yet.   
  - Added support for YCbCr OpenGL texturing (only tested with GL_MESA_ycbcr_texture)

      * only one overlay at the moment
      * Vector graphics /images can be drawn above the overlay if the video output supports dest color keying
  - Changed 3D mesh object to be slightly more compact (colors and normal)
  - Unified focus model for SVG and MPEG-4. MPEG-4 focus can only be used through tab/-tab (no north/east/.. navigation)
      * The MPEG-4 focus is based on the groups (2D/3D) presenting interactive features (sensors)
        * keyboard mapping for sensors is:
            isOver triggered when focus moves in(isOver=TRUE) and out (isOver=FALSE)
            isActive triggered when ENTER key is pressed (isActive=TRUE) and released (isActive=TRUE) 
            direction keys with or without SHIFT to simulate mouse move
        * Layout node is considered as a sensor when scroll_rate is 0, so that the user can scroll the layout
      * The focus is by default on the UA (GPAC), not on the content.              
  - Added support for inplace text edition in SVGT and in MPEG4
      * support for clipboard paste at current caret pos (win32, wxWidgets - no WinCE/symbian yet) 
      * VRML/MPEG4/X3D: this is not standard, enabled with "EDITABLE" present in text->fontStyle->styles. 
            Added because StringSensor does not allow for in-place editing of the string
  - Added support for text selection in MPEG4 (non standard) / SVGT with clipboard copy (win32, wxWidgets - no copy for text+tspan - no WinCE/symbian yet)

     - both plugin now support browser navigation (ie link to html within MPEG-4 content)
     - Plugins can be used to modify the presentation from a parent HTML doc
     - check sample files in regression tests for more details
  - iTune tagging support, (patch from Andrew Voznytsa with slight modif). Tagging can be done with MP4Box -itags option. The tags are passed in a single string, separated by ':', formatted as 'tag_name=tag_value'. Supported tags names are: album, artist, comment, compilation, composer, created, disk, encoder, genre, name, tempo, track, tracknum, writer.
     NOTE: to make sure you mp4 is importable on an iPod, you must:
       - use .m4a extension
       - specify the right brands: MP4Box -brand "M4A " -ab mp42
     This process is automated in MP4Box for all file with extension .m4a
  - added MPEG-1/2 raw importing (extensions: .m1v and .m2v).

  - initial IPV6 support
  - MP42AVI is now deprecated. MP4Client can now be used to produce uncompressed bmp/raw/AVI, dumping the complete presentattion rather than just BIFS scenes (audio is currently not extracted). Usage:
     MP4Client -bmp 1-2.5-3 file.mp4 take screenshots of file.mp4 aty T=1, 2.5 and 3 seconds
     MP4Client -avi -fps 15.0 -size 176x144 file.mp4 produces an uncompressed AVI of resolution 176x144, framerate 15
     MP4Client -avi 4-10 file.mp4 produces an uncompressed AVI of the scene between 4 and 10 seconds
      Check MP4Client man page for more details.

  - added support for importing AMR/SMV/EVRC file missing their magic number
  - moved all language handling to both ISO 639-1 (2 char code) and 639-2 (3 char code), as 639-1 is used in SVG.
  - removed old XML parser, all parsing now relies on a new GPAC SAX parser (avoid dependency on libxml when unneeded).
    - support for progressive loading support for XMT and X3D files.
    - new svg_in module using gpac sax parser (supports progressive loading too)
    - cf configuration.html or man gpac for more info on progressive loading control
  - added 'define' support in BT - to use it just do:
     #define symbol blab labl a
    and reuse the symbol in the BT text. This may be quite buggy, but it can be usefull
  - support for Scene Carousel in hinters, core and rtp reassembler. Currently only BIFS and BIFS+AV can be use the scene carousel, carouseling of 
    static data (eg images) is not supported. The OD data must be embedded in the IOD a la ISMA.

	- integrated ogg lib in gpac (<gpac/m4_ogg.h>), and added ogg/vorbis and ogg/theora importers to mp4 - THIS IS NOT STANDARD AT ALL. 
		The current syntax is to put needed headers in the MPEG-4 DecoderSpecificInfo, with the following syntax:
			u16 sizeof_header;
			char *header_data;
		for each header (quite similar to what is found in qtcomponents). Vorbis ObjectTypeIndication is 0xDE, theora ObjectTypeIndication is 0xDF.
		Need some more testing before filing a request to mp4ra.org.
		Streaming possible as MPEG-4 streams, Vorbis RTP packetizer still to be done.
