maximum_reuse defaults to 0.2 - which was also the hard-coded value in
POV-Ray 3.6.
In a nutshell, the parameter governs the maximum effective radius of
radiosity samples in just the very same way as minimum_reuse governs the
minimum effective radius; a value of 0.2, for instance, means that a
sample at X units distance from the camera will be re-used within a
radius of at most 0.2*X units.
Obviously this parameter should be > minimum_reuse at all times. While
reducing the value will almost certainly increase rendering times, it
might be useful e.g. in cases where you have wide open spaces with a few
comparatively small objects, which the radiosity pretrace might tend to
miss otherwise.
