I'd expected that the areas "far outside" of the Mandelbrot set (outside 
of the red cylinder) would have "low" values, so they are far "outside" 
of the isosurface. But they aren't, so the result is that the whole 
contained_by box is filled.

Is it a bug how mandel pattern & isosurface work together or is the bug 
in my scene file? :-/
