  This is exactly my point and exactly what I don't understand in Ken's
opinion.
  It seems like he thinks that he automatically knows how a builtin pattern
is used and what is its syntax, but he will not know the same things for
a macro.
  I just wonder how this can be possible. If someone tells me that there's
a builtin pattern called 'spiral2' in povray, I have not any idea what would
be its syntax or how it is used or how it will look like (I can guess from
the name, but will probably guess wrong in this case).
  What I make in this case is to look in the povray documentation how this
pattern is used and what does it do.
  How this differs from a standard macro goes beyond me.
