I just tryed PPM from 5 to 16 bit per chanel, and only at 8 does the 
result is correct. Under 8 bits I get heavy random colours banding, over 
8 bits I get "random" coloured pixels all over the object and the 
background turns to black if a plain colour, a sky_sphere goes psychedelic.

No problem using PNG at the same depths.
