Graeme, btw. as this comes into my mind again now: For the reason you mentioned 
above, it may possibly be also interesting to find a white point location with 
minimum distance from [255,255,255] in _RGB space_, which is still located on 
either the daylight or blackbody locus.

My feeling is that "dispcal -t <temp> ..." (where <temp> is the temperature 
reported by "dispcal -R ...") seems to compromise more RGB steps than necessary 
for obtaining a WP located on the daylight or blackbody locus.
