太妙了！感谢 pull！ 测试下来 火狐上的绘制报错确实是高度错误导致的。 |

感谢认同🤣 僅支持案頭端 Chrome、Edge 瀏覽器。
Safari、Firefox 下存在嚴重問題 |
是的，终于可以把这个提示去掉了🤣 Safari canvas 系列 API 的内存占用限制通过共用绘制元素也已经基本解决，正好一起上线www 🥰 |

我去复盘了一圈，总算好像理解了这个 bug 的根源，Safari 会在 字重 600 以上时 通过简单的横向重复渲染字型让字体看起来变重，在这个过程中没有考虑阴影之类的细节 🤬🤬🤬 不愧是 Safari、仿佛现代 IE6，每次都能在她身上发现匪夷所思的神奇特性 |

firefox的问题
make.js里
metrics.fontBoundingBoxDescent和metrics.fontBoundingBoxAscent在firefox下不支持。我做了适当的替换，换成了用fontSize表示。不知是否合适。（我测试了一下应该没问题）safari阴影
其实我没有遇到 issue#1 那种三叠重影，只是发现阴影有点重。我在 make.js 中的
ctx.shadowBlur做了适当的修改。当然系数我不知道多少合适，有待讨论，我标在 221 行注释里了。
