976 Note : in all these conversion, it would be best to average the averaging
977 pixels to get the color of the pixel that will be color-keyed to
978 prevent 'color bleeding'. This will be done later on if ever it is
979 too visible.
980
981 Note2: when using color-keying + alpha, are the alpha bits part of the
982 color-space or not ?
