NetWar Graphics Engine revision history                      George Hoffman
---------------------------------------------------------------------------

v1.10    Got around to sticking the code for enemies in there, and 
          modifying it for the new system
         Sketched out menuing system - not really part of the engine,
          but what the hell

v1.03    Optimized wall calculation : 50 - 60% speed increase on
          long views
         Fixed wall-floor/ceiling meshing problem using a hybrid of
          the old and new angling system
         Optimized some critical timer-tick code

v1.02    Added a lot of little stuff - optimizations
         New angling/turning technique - takes less memory, and now
          3600 possible facing directions instead of 128
         New, MUCH more accurate ray-casting - cleans up
          all the little "warps" (duplicate wall slices)
          Little slower, I think, but not by much
         Cleaned up movement speed handling

v1.01    Fixed MAJOR but SUBTLE bug in keyboard routines.  Interrupt 
          15h is trapped, and the previous interrupt was being called
          in a manner which would satisfy many system calls, but not
          those used by EMM386.EXE.  This bug was transparent to me, 
          as I use QEMM.  The net effect was that it either killed
          you right off with a system crash or corrupted your memory
          and hit you later when you tried to run a well-behaved app.
         Implemented system independant movement speed.
         Cleaned up memory de-allocation to save headaches later

v1.00  First release
