i defer to you .... i'll reread the doc and see if i can figure out what led 
me to believe that the default behavior for gamma correction has been around 
since 3.6.1

these scene files have glass.inc but MAY not call glass_old textures. i'll 
take ownership for making those changes.

Stephen I owe you two files as you're already working on the incdemo files. 
I'm going to speak up for the advanced/animations group of files. I will 
deal with the remaining files when someone speaks up for the groups that 
they are in. I will also post the revised glass/glass_old.inc files so both 
of you  (Stephen/Sabrina) can pick those up. Zip format OK? Give me a couple 
of days to get this done as I'm juggling several things (feast or famine) 
right now.

Jim
