Great! Nice and consistent with the other newer finish defaults.

I''m curious about the reason for this change. (Personally, it will take some
getting used to.) Is it perhaps due in some philosophical way to the change of
#default ambient to 0.0 (where pure shadows would now be pure black instead of
'lit' with ambient 0.1? Meaning, it would be hard to discern a previously
un-pigmented object-- black until now-- from it's now-black shadow duo to
ambient 0.0?)

I don't usually mess with   right  x*image_width/image_height,  and run
different aspect-ratio images simply by choosing another entry in quickres.ini.
(1280X720 instead of 800X600, for example.)  Will this change affect the visual
result of the render (in some *strange* way), if I continue to use my simple
scheme? Sorry if my question seems naive, but it's not clear if my quickres.ini
entries would also need changing.
