/****************************** Module Header ******************************\
*
* Module Name: PMBITMAP.H
*
* OS/2 Presentation Manager Bit Map, Icon and Pointer type declarations.
*
* Copyright (c) International Business Machines Corporation 1981, 1988-1992
*
* ===========================================================================
*
* 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.
*
* For OS/2 Version 2.0 and later BITMAPFILEHEADER2 and the other '2'
* versions of each structure are recommended. Use the non-2 versions
* of each structure if compatibility with OS/2 Version 1.X is required.
*
* ===========================================================================
*
* Comments at the end of each typedef line give the name tags used in
* the assembler include version of this file.
*
* The assembler include version of this file excludes lines between XLATOFF
* and XLATON comments.
