A good point.  How many people would get mad if I changed the syntax?

You can enclose your pattern as a pigment within a 'function' pattern.  This
way, you could do whatever you want to with the pattern before it starts
getting used as a normal.

Instead of using this:

    normal{
      crackle 0.5
      scale 10
    }

use this:

    normal{
      function{pigment{
        crackle
        color_map{[0 rgb 0][1 rgb 1]}  // might be optional
        scale 10  // scale goes here
      }} 0.5
    }

I think adding a 'pattern' pattern would be useful.  That would look like
this:

    normal{
      pattern{
        crackle
        scale 10  // scale goes here
      } 0.5
    }
