/*
 * This is the file format structure for Bit Maps, Pointers and Icons
 * as stored in the resource file of a PM application.
 *
 * Notes on file format:
 *   Each BITMAPFILEHEADER entry is immediately followed by the color table
 *   for the bit map bits it references.
 *   Icons and Pointers contain two BITMAPFILEHEADERs for each ARRAYHEADER
 *   item.  The first one is for the ANDXOR mask, the second is for the
 *   COLOR mask.  All offsets are absolute based on the start of the FILE.
