    Summary:
      Various small things to vbv conformance and divx5 compatibility.
    Revision:
      xvidcore--head--0.0--patch-6

    From pete:
    xvidcore
    ========
    * added XVID_GLOBAL_DIVX5_USERDATA global flag
    * removed the bvop delay warning text ("warning: nothing to output),
      as this often confuses joe user.
    * minor changed to closed gop image_printf statement:
      s/"DX50 BVOP->PVOP"/"CLOSED GOP BVOP->PVOP"
    * additional comments for low_delay_default mode within decoder_decode()
    * divx userdata string: s/DivX999b000/DivX503b1393. this has been
      suggested by dxn for improved hardware compatibility [nb: i dont
      have a hardware player to confirm this]
    * vbv_peakrate constraint is ignored if <= 0
    
    vfw frontend
    ============
    * dxn profiles now confirm to "DivX Certified Profile Compatibility v1.1",
      February 2005. this document was provided by DivXNetworks, USA. when a
      dxn profile is selected, strict conformance is enabled:
      - force 1:1 picture aspect ratio
      - disable bframes if interlacing is enabled
      - force maximum of 1 consecutive bvops for the portable and ht profiles,
        2 bvops for the hd profile
      - always write divx 5 userdata string to bitstream
      - force packed bitstream option
    - updated dxn vbv parameters
    * added PROFILE_4MV flag. 4mv is now disabled for the dxn handheld profile.
    * moved PROFILE_AS/PROFILE_ARTS/PROFILE_S to config.c
    * profile[].max_bitrate now measured in bit/sec (not kbps)
    * profile->level box: widgets are now greyed-out if they are not used.
    * increase vertical size of profile drop down list.
    * about box button: s/Dismiss/OK

2005-03-18 16:58:08 GMT	                                	patch-121

    Summary:
      ME work
    Revision:
      xvidcore--head--0.0--patch-121

    From Isiibar:
     - Cartoon mode bugfix
     - New lambda tables for R-D motion search. The old tables were
       obviously taken from h.264, which uses a logarithmic quantizer
       scale. This lead to bad results at very low bit-rates. With this
       patch, compression efficiency at low bit-rates is greatly improved.

    Summary:
      Long standing bug in 2pass2 code. Double overflow accumulation.
    Revision:
      xvidcore--head--0.0--patch-112

    From pengvado (x264 developer, sorry i don't have your realname):
     * rc_2pass2_after accumulates overflow twice, once in each I/PB subcase
       and then in a common code path. The common path was just supposed to
       store the stat struct entry error for statistics (even if they're unused)
