Hi Thorsten,

my scene *is* complete: it does render, resulting in a thin "line" with
color <63,63,63>/255, an approximation of <.25,.25,.25>. As sascha wrote,
my light source is "ambient 1". Not only the border is anti-aliased: try
+R9 and wait many minutes for the pure black background to be rendered.
Of course there is no visible effect on this background, but time is
consumed depending on +R. If this time is not being used for anti-
aliasing: what else does POV-Ray do during this time and why does it
depend on +R?

Still confused ...
