This is an expensive way to copy a GIF. The source is included as a skeleton
for more sophisticated filters using DGifSlurp() and EGifSpew(). See the
source in the util directory for details.<P>
I suppose this does have some utility as a test of DGifSlurp() and EGifSpew().
The output should be bytewise identical to the input.<P>
