汉字可以看成由形状和字体构成。 如果我们能创建一种抽象的形状描述，结合指定的字体描述， 用一个通用的渲染引擎，计算机不需要巨大的汉字字库就能画出这种字体的任意字号。

Chinese characters can be disassembled with shape and font. If we can create an abstract shape description, with certain font description and a common render engine, computer can draw Chinese characters with the font in any size without huge Chinese characters library.
