Glare studies (e.g. photovoltaic panels) -- [BETA]

Note that this is very preliminary functionality; you might want to talk to Patricio before using it.

The sun-study functionality (mostly used for shadow studies) can now also be used in the context of glare studies. For example, it can be used when evaluating photovoltaic panels, which, in this version, can be modelled using mirrors (3d-poly elements with material/texture "mirror"/"Spiegel"); see Fig. 1.

❑	Note: In order for mirrors to be able to illuminate elements in the your ray-traced model, you need to activate the illumination option Mirrors can illuminate by reflecting light from light-sources [...; slower]. (For efficiency, this option is not selected in the default settings.)
