之後的做法

• 先做一個前處理註冊器，註冊下列的前處理
  • 中英文間距
  • 換行點
  • 空白轉為 [glue]
• 前處理完成字串後，必須要：
  • 算出字元的Box
  • 利用 frame/box 資訊分行、分頁
  • 然後算出每個Box的x, y, page
  • 最後納入排版

排版語法

使用lisp表示，但其實是陣列

  (hglue 寬度 伸展值)
  (vglue 高度 伸展值)
  (bp 原始模式 斷行模式) ; breakpoint
  (br) ; force newline
  (em 數字)
  (ex 數字)
  (span {"font-family" : "Noto Sans" , "font-size" : 16 })
  (vbox 高度 內容)
