-------- repeating along each path ----------
 
'Space type':
            'count'      - put N objects evenly spaced along path
            'fixed'      - use N pixels of space for objects
            'fit'        - use full size of the object (even if scaled); fit as many as possible
            'scale'      - use scaled size of the object; fit as many as possible
            'fit-rand'   - as fit but randomise the spacing
            'scale-rand' - as scale but randomise the spacing
           
'Value'      - the count or spacing value N points
 
'Adjust fit' - percentage tighter or looser fitting
 
'Cycle':
            'all'    - all objects are placed at each point
            'random' - random choice of object at each point
            'cycle'  - cycle through the objects
 
'Fade'       - fade the objects along the path
 
--------- placing on path ---------------------
 
'Style':
            'off'    - no rotation
            'rotate' - rotation by fixed amount each step
            'vibra'  - random back and forward 'vibration'
 
'Vibrate'  - degrees of vibration
 
'Rotation' - degrees of rotation
 
'Centre x','Centre y' - centre of rotation % offset from bottom left
 
'Jitter'   - if the objects are to scatter across the path
 
'J Amount' - % of the max size of the objects (scaled if appropriate)
 
--------- scaling ----------------------------
 
'Main scale'    - an overall scaling of the objects
 
  
'Growth':
            'increase' - smallest object at beginning of path
            'decrease' - largest object at beginning of path
            'off'      - no scaling of objects along the path
 
'Scale'         - the %age scaling at each step along the path
 
'Front to back' - true if the later objects go behind the ones in front
 
------- group repeating -----------
 
'Repeat'  - true if the generated path is repeated
 
'Count'   - how many times it is repeated
 
'Offset x','Offset y' - the direction of the repeat
 
'Scale'   - repeat increases/decreases in size
 
'Amount'  - % scaling per repeat
      
'fade'    - fade with each repeat
 
   
------- selection and action ------------------
 
'Make symbols' - if true, 'set Objects' causes the objects to be symbolised
 
'Set Objects'  - remembers the selected objects to be repeated
 
'Set Paths'    - remembers the selected paths along which to repeat
 
'Run Execute'  - processes the items
