scaled preserve_luminosity code by 64 (256*64=16384; 360*64=23040)
changed (float) to f; thanks for the tip IanB!

0.3 branch should have 16bit or float internals. Going camping so it might be done in a week or 2, unless someone wants to pick it up.
@IanB
I didn't touch the transfer tables... I believe they have to change in order to go from 8 bit to xx bit. All I did was scale by 64 what the hsl functions pass around; which should help seeing how I'm rounding down.
