  avcodec/sanm: fix codec3
  
  codec3 is codec1 which writes zero values instead of skipping them.
  This fixes a lot of RA1 videos.

  avcodec/sanm: disable left/top for fullscreen codecs
  
  The block-based codecs 37/47/48 work on the full frame, and there's no
  existing LucasArts game video that uses left/top offsets for these,
  as it doesn't make sense. Ignore the left/top parameters for these codecs.

  avcodec/sanm: better frame size detection for old codecs
  
  The size of the video frame (FOBJ) of the old codecs (ANIMv0/1/2) can
  very reliably be determined:
  - ANIMv0/1 (=Rebel Assault 1) uses a 384x242 internal buffer for
    everything.  The codec parameters only describe the size and offset
    of the specific FOBJ on that buffer.
  - ANIMv2 titles usually use one of the fullscreen codecs (37/47/48)
    as first FOBJ, and their dimensions can generally be trusted.
  - RA2 uses 424x260 as internal buffer, use that if encountered:
    08PLAY.SAN does not use codec37 so we need to guess using the
    codec coordinates.
  - ignore sizes smaller than 2x2 or larger than 800x600.
  - some game videos have an initial fobj with either 1x1 or -1x-1
    pixels in size, ignore them with a warning (Full Throttle
    and the Rebel Assault 2 xxRETRY.SAN videos).
  
  Once a known/valid dimension set has been discovered, use it and
  don't change it for subsequent FOBJs, rather clamp the large frame
  to the determined dimensions.
  
  Tested with RA1, RA2, Full Throttle, Dig, Outlaws, SotE and MotS
  videos.

  avcodec/sanm: codec37: reimplement comp4
  
  Compression 4 code 0 means copy from delta buffer without mv,
  AND start of a skip run.  This gets rid of the extra case and column
  index manipulation and implements this as it is implemented in the
  original game exe, i.e. as a special case for after mv copy.
