I called it a bug because ior has been moved from finish to interior
because ior has to be constant in the whole object to prevent that a ray
enters at one ior and leaves at a different one. But when two object of
different ior are merged / intersected exactly the same thing happens.
I see now that overlaping of transparent object in union cannot be checked
at parsing time and checking it during rendering would things slow down.
But in the case of merge/intersection a warning at parsing time could be
issued.
