Hi all:

  Here are some attempts to replicate the results of Mael HDRI patch
with regular image_maps, ambient and radiosity. This is not a try to
invalidate the need for a patch, but only a search for a way to do it
with any POV-Ray scene. I liked very much the tests done by Gilles and
others, but I wanted to do it with something more than a limited set of
premade HDR maps. And as the only camera that I have is POV...

  In my usual lazy-curious way of thinking, I figured that the important
part here was not the H but the DR. That is, the image used needs to
have a dinamic brightness. The problem, as Ive said, is that on a
regular photo (or POV image), the sun and a sheet of paper are both rgb
1. But with POV, the scene for the map can be carefully created with a
"pseudo-dinamyc" brightness, making light sources much brighter than the
other objetcs on the scene. That is how I've setup the light for a
spherical shot on the "office" scene, using the resulting image as the
fake HDRI for the "reflective balls" scene.

  Well, not as spectacular as real HDRI, but I needed to keep busy the
CPU with something while writting the docs for the next version of
ligthsys...
