Fast datatype for displaying GIF files.

A very fast GIF Datatype

 Main features:

    o	SPEED.  Try it, after using this you wont want to be without it!
    o	Supports most gifs (only some esoteric, and mostly unused features
    	of the GIF8?a standard have been ignored)
    o	Uses async file reading for greater performance - on an A1200 will
	load a picture the same speed off of floppy as off of hard drive!
    o	100% Assembly language, very optimised.
    o	Custom chunky to planar conversion, that is reasonably fast 
        (a version using WritePixelLine8() runs about 50% the speed of 
        this version)
    o	Now works with all 68000 series CPU's (i hope)
    o	Now supports transparent gifs ('copy' a transparent gif from
        multiview and then paste it as a bruch in DPaint - NEAT eh?)
    o	Its FREE! (this is of course the best bit)


Main limitations: (hey, its not _perfect_ after all)

    o	OM_WRITE BOOPSI method not yet implemented.  Expect this in a future
    	release.
    o	Only decodes pictures with a global colour table.  Most gif loaders
    	do the same, and most writers write them.
    o	Ignores any local colour tables (but still decodes picture).  Could
    	lead to a bad palette.
