The behaviour of the render window has changed in the 3.7 versions over the 3.6
versions. Opinions?

Gray scale output:
In 3.7 .ini file,
Output_to_File = On
Output_File_Type = N
Grayscale_Output=true
Display = On
Gives a color render window, and a gray scale saved image.

In 3.6 global settings
hf_gray_16
Gives a gray scale render window, and a gray scale saved image.

Partial ouput, start end column/row and radiosity (pretrace_start/end):
In 3.7 .ini file,
+ac +sc0.378717 +sr0.526882 +ec0.522692 +er0.679570
for example.
Gives the area in question and 'may' give radiosity blocks to the right and
bottom.

In 3.6 .ini file,
+ac +sc0.378717 +sr0.526882 +ec0.522692 +er0.679570
for example.
Gives the area in question only.

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.
