icon scale的用法和樣例：
例句
- And this is why we design each icon size to scale, instead of relying on a single vector file.
這就是為什麼我們按比例設計每一個尺寸的圖標，而不是僅僅依賴一個矢量圖。 - At this scale, the curving shore of the main landmass is visible, and the tanks are so small that they are now represented by icons.
在這個比例下，主大陸的彎曲的海岸線已經可以看到了，坦克因為太小了只好用圖標來表示。
