Ain't this sweet?

PNG properly defines how gamma should be handled in the presence of a 
gAMA chunk.

POV-Ray 3.6, when used with assumed_gamma, respects this definition 
flawlessly... for 24- and 32-bit images, that is.

For 8-bit color palette PNG images, POV-Ray 3.6 doesn't give a damn 
about gamma correction.

Likewise, the PPM format properly defines how gamma should be handled 
*always*.

POV-Ray 3.6 gives a piece of sh*t about this definition.


So, how should one go about this in POV-Ray 3.7? Emulate all those 
crappy details? If so, when? Only when #version is set to 3.6? Always 
when the legacy assumed_gamma statement is used (which is supposed to 
not be used for new scenes)?


Can of worms indeed...
