Given a color in a display dependent format, these functions extract one of the red, green, or blue components (ranging 0-255). Example:

   int r, g, b, color_value;

   color_value = _getpixel15(screen, 100, 100);
   r = getr15(color_value);
   g = getg15(color_value);
   b = getb15(color_value);
