Unbiased Diffuse Illumination:
- UberPOV allows to disable the caching of radiosity samples, by
following syntax in the global radiosity block:
It also changes the way the secondary ray directions are chosen, and
effectively turns the radiosity algorithm into a purely stochastic
algorithm to compute diffuse illumination.
Most radiosity settings are without effect in this mode, except for the
The current implementation does not translate classic radiosity
into useful parameters for this mode of operation; it is therefore
recommended to use a much lower setting for the "count" parameter than
typical with standard radiosity.
This syntax extension can be tested for using the #patch directive or
patch() function with the patch name "upov-radiosity-no_cache"; the
implementation is version 0.1.

Add support for stochastic diffuse computations.
Specifying `no_cache` in the global radiosity block will disable
caching of radiosity samples,
and use a more random algorithm to generate secondary ray
directions, effectively using the
radiosity code for straightforward stochastic computation of
