The first time i visited, the starfields where identical, except for the 
surrounding backgrounds.

This time, they are not.
The "original" and the 3.6.1 are identical.
The 3.7 is MUCH brighter. It shows details that are NOT visible in the 
other images even with the brightness cranked to the max for the firsts, 
with the brightness at it's lowest setting for 3.7.

Whatever my settings, the top and bottom parts of the rendered images 
never match.
Notably darker with 3.6.1, much lighter with 3.7.

On the other hand, I get no undesirable effects when I use a POV-Ray 
generated image as an input in another one. Brightness, saturation and 
colour balance don't change. I normaly use PNG as file format.
