BUGS:

general:

  add copyright blocks

  add profile support

  add bit peeling

schropack.c:

  figure out how to push disjoint buffers if possible

schrodecoder.c:

  trick modes (decode_prediction_only) should be made into parameters

  sanitize code layout

schroencoder.c:

  sanitize code layout

  don't use metric in SchroMotionVector

schrohistogram.c:

  rename ilogx/iexpx to something sane

schroparams.c:

  write function for determining optimal index for various parameters

  move data to schrobitstream.c

schropredict.c:

  implement "how did we get this" bitfield

schrowavelet.c:

  implement 32-bit code

schrooil.c:

  move stuff to liboil

  add arrays of arrays to liboil
