Update target directory used by extended rendition.
    
    - Previously, when the target directory was created, foreground was
      used first and background later. Background information is reduced
      to one or two values mainly (e.g., white and transparent) but
      foreground information has more values. This update updates
      extended function to invert color information order in the target
      directory using background color first and foreground color later.
    
    - Add 26 and 52 values to list of default height values.
