The Max Level entry is for max_trace_level and always apply. The 
presance of any isosurface don't mather.
This mean that, in this case, a single ray can have up to 20 reflections 
or refractions before POV-Ray gives up.

There are no messages regarding max_intersections. 
max_intersections/all_intersections applys only to isosurfaces that are 
part of difference/intersection.
