I've been doing some systematic tests and tweaks. So far I can reproduce 
the appearance of pre-assumed_gamma scenes in scenes with assumed_gamma 
= 1 in cases where the following parameters vary:

1. lighting color
2. pigment color
3. ambient (finish, not global_settings)
4. diffuse


I haven't figured out filter and transmit yet. I'm guessing it will 
require replacing the linear pigment/gradient functions in the original 
scenes with exponential ones.
