              >>> glyph.clear()
  
          This clears:
  
          - contours
          - components
          - anchors
          - guidelines
          - image
  
          It's possible to turn off the clearing of portions of
          the glyph with the listed arguments.
  
              >>> glyph.clear(guidelines=False)
