 *	\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.
