- collectFloats
  
  public void collectFloats(CssContext c, Layer layer)
- collect
  
  public void collect(CssContext c, Layer layer, Box container, int shadowPageNumber)
  
  The main box collection method. This method works recursively to add all the boxes (inlines and blocks separately) owned by this layer to their respective flat page display lists. It also adds clip and setClip operations where needed to clip content in overflow:hiddenblocks.
