SYNOPSIS

       #include <allegro.h>

       void set_screen_blender(int r, int g, int b, int a);

DESCRIPTION

       Enables  a  screen  blender  mode  for combining translucent or lit truecolor pixels. This
       blender mode lightens the colour of the destination image by multiplying  the  inverse  of
       the  source  and  destination  colours.  Sort of like the opposite of the multiply blender
       mode.
