[xiph-cvs] cvs commit: theora/lib toplevel.c

[Ralph Giles]

  Modified:    lib      toplevel.c
  Log:
  Move the in-loop filter limit coefficients table from the end of the
  setup packet to the beginning. It's a fixed-length table, so this lets
  us keep byte alignment for more of the data. Suggestion from Derf.
  
  THIS IS AN INCOMPATIBLE BITSTREAM CHANGE.
