[Radiance-general] DGI Glare indices

[Jan Wienold]

Hi Don,
values less than 0 doesn t make sense in principal, but are mathematical possible when you look at the equation. (log function)
It means that you consider areas with a very low luminance as a glare source or your background luminance is very high.
