  4. ;  Supposed to look vaguely like roughly carved wood. Chipped away if you will.

  6. ;  Options: Text String - the string to make the logo from
  7. ;           Font        - which font to use
  8. ;           Font Size   - how big
  9. ;           Chip Amount - how rought he chipping is (how spread the bump map is)
  10. ;           Blur Amount - the bump layer is blurred slighty by this amount
  11. ;           Invert      - whether or not to invert the bumpmap (gives a carved in feel)
  12. ;           Drop Shadow - whether or not to draw a drop shadow
  13. ;           Keep bump layer? - whether to keep the layer used as the bump map
  14. ;           fill bg with pattern? - whether to fill the background with the pattern or leave it white
  15. ;           Keep Background - whether or not to remove the background layer
