-----------
Indirect lighting: added clamping mechanism for virtual point lights, to reduce artifacts such as random bright spots.

As the code is still relatively untested (and I'm not 100% even sure to have correctly understood the paper on this), I'm also adding a temporary toggle to disable it, in order to easily perform tests and comparisons.
