/**************************************************************
*  All WDT's start with 0x4d564552 (REVM), 0x04, 0x12,        *
*  0x4d504844 (DHPM), and 0x20.  All of those are 1 byte      *
*  in length.  The next byte contains the flags. 0x01 is      *
*  for WMO-based maps, and 0x08 is probably for maps that     *
*  contain phasing.  The other two flags are unknown. After   *
*  the flag byte, there appears to be 7 empty bytes. After    *
*  those bytes, all WDT files seem to contain: 0x4d41494e     *
*  (NIAM), and 0x8000 (weird C symbol).  After these bytes,   *
*  there is a giant array of 64x64 bytes which contains 0x0   *
*  for ADT files that don't exist and 0x1 for ADT's that do   *
*  exist.                                                     *
