ies-files represent the light distribution of a source. This is
important if you want to simulate an architectural scene.

If there was a "parallel" area light in povray, one could write
the macro by modeling the light distribution with plane light
sources with different amplitudes.

I wonder if it makes sense to try something like this with a
sufficient amount of spotlights - though the "resolution" would
give bad performance.

I would like to try povray to simulate the behavior of some
materials in an interior scene, with the effects of different
light sources. At the moment this is impossible, as noone has a
real point light or spot light at home.
