   1 /*
   2 Several constants are re-defined under different names.  This is simply
   3 because they are used for different purposes.  They do exactly the same thing,
   4 it is just to make the code easier to read / understand
   5
   6 Please note the 90% of the code in here was taken straight out of Allegro,
   7 I only made a few small changes to the drawing routines.
