> On testing saturation today, I did notice a potential bug with that setting. For my test raster, I set the saturation to 1 and the difference between that setting and 0 was quite large. If I move to 2, 3, 4, and so on, the differences are very small and incremental.
> I'm wondering why the leap in saturation from 0 to 1? Is something incorrect in the algorithm calculating saturation? It seems as the values between 0 and 1 need to be handled to make the 0 to 1 change as incrementally small as the 1 to 2.

Can you create a bug report about this and attach your raster to it
(if possible)? I'll take a look at this and see what's happening...
