[Radiance-general] displays

[Gregory J. Ward]

Thanks to Thomas for offering that thoughtful reply.  I'm a little  
swamped at the moment...  The files I gave to Yuni under the subject  
"glare on monitor screen" a couple weeks ago are the best I have to  
offer at the moment.  Note that I used a "mixfunc" type to get the  
diffuse, specular, and emission to happen together in one material.   
The "glass" isn't really appropriate, for the reasons Thomas  
mentioned among others.
