Add a port of Mitsuba, a research-oriented rendering system in the style

of PBRT, from which it derives much inspiration.  Written in portable C++,
it implements unbiased as well as biased techniques, and contains heavy
optimizations targeted towards current CPU architectures.

Collada importer and CPU affinity are currently not supported on FreeBSD.

+Mitsuba is a research-oriented rendering system in the style of PBRT, from
+which it derives much inspiration.  It is written in portable C++, implements
+unbiased as well as biased techniques, and contains heavy optimizations
+targeted towards current CPU architectures.  Mitsuba is extremely modular: it
+consists of a small set of core libraries and over 100 different plugins that
+implement functionality ranging from materials and light sources to complete
+rendering algorithms.
+
+In comparison to other open source renderers, Mitsuba places a strong emphasis
+on experimental rendering techniques, such as path-based formulations of
+Metropolis Light Transport and volumetric modeling approaches.  Thus, it may
+be of genuine interest to those who would like to experiment with such
+techniques that haven't yet found their way into mainstream renderers, and it
+also provides a solid foundation for research in this domain.
+
+Mitsuba comes with a command-line interface as well as a graphical frontend to
+interactively explore scenes.  While navigating, a rough preview is shown that
+becomes increasingly accurate as soon as all movements are stopped.  Once a
+viewpoint has been chosen, a wide range of rendering techniques can be used to
+generate images, and their parameters can be tuned from within the program.
