Well, actually the render window behavior has not changed: In both 
versions, preview is color if the hf_gray_16 is absent - which just 
happens to be enforced by 3.7 ;-)

But I guess it makes sense to change POV-Ray 3.7 interpretation of the 
new Grayscale_Output option so that it affects both file and preview 
output, as it is such a fundamental setting that it goes beyond ordinary 
file format options.

This is a side effect of the architectural changes in POV-Ray 3.7, and I 
guess nobody has paid attention to this detail before. I guess it should 
be possible to fix, but some thought will have to go into it.
