Represents a PAP FKP. The style properties for paragraph and character runs are stored in fkps. There are PAP fkps for paragraph properties and CHP fkps for character run properties. The first part of the fkp for both CHP and PAP fkps consists of an array of 4 byte int offsets in the main stream for that Paragraph's or Character run's text. The ending offset is the next value in the array. For example, if an fkp has X number of Paragraph's stored in it then there are (x + 1) 4 byte ints in the beginning array. The number X is determined by the last byte in a 512 byte fkp. CHP and PAP fkps also store the compressed styles(grpprl) that correspond to the offsets on the front of the fkp. The offset of the grpprls is determined differently for CHP fkps and PAP fkps.
