    PDF interpreter - cope with legal but sub-optimal indirect /Pattern
    
    No bug, the report is from a customer who wants the file to be treated
    confidentially.
    
    The files uses a Pattern colour space, which it defines in a highly
    peculiar fashion:
    
    stream
    ....
    /CS0 cs /P0  scn
    
    ....
    endstream
    
    CS0 is defined as:
      /CS0 22 0 R
    
    and object 22 is:
    
    22 0 obj
    [ 23 0 R ]
    endobj
    
    23 0 obj
    /Pattern
    endobj
    
    The PDF interpreter wasn't prepared to handle the name being an indirect
    reference.
