 * The miGIF compression routines do not, strictly speaking, generate files 
 * conforming to the GIF spec, since the image data is not LZW-compressed 
 * (this is the point: in order to avoid transgression of the Unisys patent 
 * on the LZW algorithm.)  However, miGIF generates data streams that any 
 * reasonably sane LZW decompresser will decompress to what we want.
 *
 * miGIF compression uses run length encoding. It compresses horizontal runs 
 * of pixels of the same color. This type of compression gives good results
 * on images with many runs, for example images with lines, text and solid 
 * shapes on a solid-colored background. It gives little or no compression 
 * on images with few runs, for example digital or scanned photos.
