Slim fast for wcIIcam0.2

I think compression did not work very well for cpia0.2 from the first
version. It is interesting that in the Jean Merliot version (wcIIcam0.2)
the compression works pretty well. Are there different compression
algorithms? Is it possible to replace the bad one with the good one?
