[DISCUSSION] Vector Fonts Support

[!NOTE]
This is a draft about better font support in Processing. This issue will be updated based on discussion and feedback from the community.

Currently Processing handles fonts only as bitmaps. It should use vector fonts.

Historically, OpenJDK has relied on ICU4J for Unicode support.

Variable fonts

It seems like OpenJDK has integrated Harfbuzz as a replacement for ICU4J, which has a number of benefits, including variable font support. More research is needed.

该 issue 没有列出源文件、测试或入口点。首先查看 Processing 当前对位图字体的处理方式，以及链接的 OpenJDK、ICU4J 和 HarfBuzz 参考资料；当项目已经确定并记录了矢量字体支持方案，包括可变字体问题时，这项工作就完成了。
