the noise is definitely dithering, since dithering accomplishes colour blending
using patterns similar to noise. it shouldn't be so noticeable in general use,
but, trying to accomplish smooth gradients with only 1/4 of the colour values
per channel is difficult.

haven't been able to sort this out, catalyst isn't really an acceptable
alternative.
