Add support for euclidean distance in LAB space (though it doesn't
...
give good results and doesn't seem to be much faster anyway)
Clip RGB values before converting to LAB, to allow more easily
experimenting with not clipping the result of dithering, i.e. allowing
quantization error to take RGB values out of the 0..255 range. This
may not improve quality but need to do more experiments.
