Add the -soft command line option which implements post-processing on
the lightmap surface to blend adjacent samples together to smooth out
hard shadow lines.

Precalculate the distance at which lights will fade to zero brightness.
For lights with inverse falloff, use the gate value to determine the
cut-off distance. Use this value to cull samples and avoid the ray
tracing overhead.
Hopefully not too controversially, I am going to default this to "on" with
a gate value of 0.001. Unless you have > 1000 lights contributing
fractional light values across your map, this is not going to make any
visible difference.

Logprint will notify the threads code that the progress meter has been
interrupted and the progress meter will re-print the next time it needs to
be updated.
Unfortunately this makes all the utils depend on the thread code, but not
a big issue.

Make the base portal vis thread safe and run on multiple threads. Use the
common thread progress indicator code.
