This class provides an abstract interface to all %BSDF plugins in
Mitsuba. It exposes functions for evaluating and sampling the model,
and for querying associated probability densities.
By default, functions in class sample and evaluate the complete BSDF,
but it also allows to pick and choose individual components of multi-
lobed BSDFs based on their properties and component indices. This
selection is specified using a context data structure that is provided
along with every operation.
When polarization is enabled, BSDF sampling and evaluation returns 4x4
Mueller matrices that describe how scattering changes the polarization
state of incident light. Mueller matrices (e.g. for mirrors) are
expressed with respect to a reference coordinate system for the
incident and outgoing direction. The convention used here is that
these coordinate systems are given by ``coordinate_system(wi)`` and
``coordinate_system(wo)``, where 'wi' and 'wo' are the incident and
outgoing direction in local coordinates.
