In order to generate a 256-entry ramp in [0,65535] which covers the full
range, one must mupliply eight-bit values not by 256 but rather by 257.
Many years back – well before the RANDR extension was written, and
before xorg at fdo – a similar bug fix was made to the DIX for converting
client-supplied eight-bit color values into sixteen-bit values.
Noticed by: Elle Stone and Graeme Gill.
