Make interactive live sketch for Shape examples

The following examples still need to be ported to JavaScript:

• Shape/Scale Shape
• Shape/Shape Vertices

However, since there is currently no support for SVGs in p5.js this has to be done another way.

I made a brief attempt at porting the Scale Shape example using p5.js-svg but it was too slow for real-time interaction. You might need to use a different library like paper.js or snap.svg

The following examples are not animated nor interactive so porting them is not strictly necessary:

• Shape/Disable Style
• Shape/Get Child
• Shape/Load Display SVG

For information on how to make live sketches for examples, please check the README on examples

从 docs/examples.md 以及其中链接的 Scale Shape 和 Shape Vertices 示例开始。检查 p5.js 中所述的缺少 SVG 支持以及尝试过的 p5.js-svg 方案，然后评估提到的替代方案，例如 paper.js 或 Snap.svg。当列出的两个示例都已移植为具有可接受实时性能的实时交互式 JavaScript sketch 时，即表示完成。
