I have 2 CGImageRef 'objects' which i have to compare.
That is working fine with the CFEqual function.
But i also need a valid (valid per contract) HashCode too.
The problem is now that these hashcodes are _always_ 0
A 0 hash code is valid (if somewhat useless). It just puts them all in
the same bucket. If you want a better hash code, then you would have
to implement that yourself (I would probably do something with the
width, height, rowbytes and maybe some other parameters of the image.
