/*
 * This is not portable between machines of differing word sizes.  To make
 * it portable, do the following things:
 *
 *     o  #include <X11/Xmd.h>
 *     o  remove the typedef for xwdval
 *     o  replace all instances of xwdval with the appropriate CARD32 ... B32
 *     o  make sure that XWDFileHeader is padded to quadword boundaries
 *     o  make sure the window name is written out quadword aligned
 *     o  create an XWDColor structure that contains the same fields as XColor
 *        but which is defined in terms of CARD32 B32, CARD16 B16, and CARD8
 *     o  convert XColor structures to XWDColor structures in xwd
 *     o  remove all xwdval casts from xwd
 *     o  pack image data before writing out if necessary
 *     o  replace casts from xwdval objects in xwud with cvtINT macros
 *     o  convert XWDColor structures to XColor structures
 *     o  unpack data after reading in if necessary
