  Gamma Handling in Beta 19

After reading Thorsten's reply in P.G., I'm putting this here.

Images output by POV-Ray 3.7 Beta display too brightly in *some* programs.

The Gimp handles them fine.

Firefox displays them too brightly.

According to the Mozilla team, the gamma is stored wrong in the file. 
It is stored as 2.2 when it should be 1.0/2.2.

I have tested force replacing the gamma with PNGCrush, and replacing it 
with .4545 (1.0/2.2) results in an image that displays correctly in all 
programs.
