One extra record of 0D bytes for each of the entities. Bit 7 of field 09 is set while the record is in use. Fields 00 and 01 are the column and the row. UpdateExtraRecord writes the adjusted x coordinate to fields 02 and 03 the adjusted y coordinate to fields 04 and 05 and the adjusted z coordinate to fields 06 and 07. Field 0B holds the width in bits 0-3 and the frame in bits 4-7. Field 0C holds the height in bits 0-5, and its bit 7 copies bit 6 of the entity flags.
