makecol8, makecol15, makecol16, makecol24, makecol32 - Converts an RGB value into a display dependent

       These functions convert colors from a hardware independent form (red,  green,  and  blue  values  ranging
       0-255)  into  various  display  dependent pixel formats. Converting to 15, 16, 24, or 32-bit formats only
       takes a few shifts, so it is fairly efficient. Converting  to  an  8-bit  color  involves  searching  the
       palette  to  find the closest match, which is quite slow unless you have set up an RGB mapping table (see
       below). Example:

          /* 16 bit color version of green. */
          int green_color = makecol16(0, 255, 0);
