/*!
* \brief lookup-table to assign different elements to partition
*
* \note here we defined up to 6 different partitions similar to
* document Q15-k-18 described in the PROGFRAMEMODE.
* The Sliceheader contains the PSYNC information. \par
*
* Elements inside a partition are not ordered. They are
* ordered by occurence in the stream.
* Assumption: Only partitionlosses are considered. \par
*
* The texture elements luminance and chrominance are
* not ordered in the progressive form
* This may be changed in image.c \par
*
* We also defined the proposed internet partition mode
* of Stephan Wenger here. To select the desired mode
* uncomment one of the two following lines. \par
*
* -IMPORTANT:
* Picture- or Sliceheaders must be assigned to partition 0. \par
* Furthermore partitions must follow syntax dependencies as
* outlined in document Q15-J-23.
