The number of displays supporting more than 8 bits per component is so 
miniscule that I don't think it is really worth worrying about.  I'm 
also not sure what display-color-cells reports on Windows 7 with 30, 36 
or 48 bit color output enabled. If it reports anything > 2^24, then it 
does not reflect reality, which is that the standard Windows API's do 
not support more than 8 bits per component.
