Attached is a rendering I did with assumed_gamma 1 and Christoph's 
latest version.  I used the chart in the POV docs and decided that my 
monitor's gamma is 2.6.  So I set this as the display gamma in my master 
ini.  I rendered to a png file and that is what is attached.  Now this 
rendering looks overexposed on my monitor.  Presumably it looks good on 
yours?

To get a rendering that looks nice and saturated and contrasty I need to 
set my display gamma at more like 1.6.  So I am still not clear on 
whether the textures are wrong or if my display gamma value does not 
match the gamma value for my monitor.
