Hi all,

I lifted the following from Alan Kong's post in
povray.announce.frequently-asked-questions.

......
3.1c               1/29/99 Chris Young
Fixed radiosity preview with odd screen size.
Reinitialized max_trace_level & radiosity_trace_level properly
Fixed token at end of file with no cr/lf or newline
......

Does this mean that in 3.1e, it'll be possible to halt a radiosity trace without
having to
restart POV?

No, it is the other way around. On platforms that don't terminate between
each render you would get some unexpected results. This is fixed now and to
continue a render with radiosity will work a bit better now.

You can observe at least the max_trace_level bug in the Windows and Mac
version of 3.1a: Create a scene and set do not set max_trace_level in that
scene In the statistics output you see something like "Max Level: 2/5" where
the 5 is the max_trace_level. Now change it to to some value other than the
default (which is 5), i.e. use 20. The you will see "Max Level: 2/20". Now
remove the max_trace_level again and you would expect "Max Level: 2/5" but
get  "Max Level: 2/20". In 3.1d this is fixed and you get as expected "Max
Level: 2/5". (I am not sure, but I think you can't see radiosity_trace_level
problem anywhere in the stats output.)
