Consider the color space as an hypercone with apex alpha=0 and base alpha=1 instead of an hypercube. Make the encoder consider very transparent colors more similar even if the hue is very different. This corresponds roughly to using the alpha as a weight for the color difference. Only 4 bits of alpha are used, because this is what dvdsub uses, and it avoids overflows. Fix trac ticket #2005.
