Create version which is compatible with p5.js v.2.0

Start by auto-detecting the version of p5.js which is running, using e.g. print(VERSION);

Current version of plotSVG (Version 0.1.4, April 6, 2025) is working okay with p5.js v.2.0.0 for me at the moment. I'm sure there are edge cases and other breaking changes, but basic geometry output seems okay. 🤞

Hi @thrly, thank you so much for the heads up and early testing!!!! This is extremely helpful to know.

For the moment (April 2025), basic shapes like ellipses and rectangles "should" work fine using plotSVG 0.1.4 and p5.js v.2.0.

The main place where I'm expecting some incompatibility is in the new implementation of the wiggly vertex commands (bezierVertex(), quadraticVertex(), splineVertex(), curveVertex()) inside beginShape() / endShape() constructions. This is discussed in the mid-April PR by the excellent @GregStanton, processing/p5.js#7734 and implemented (I gather) in custom_shapes.js. The exact differences from expected behavior may be subtle.

I plan to make any necessary repairs this summer. Until then, if anyone is experiencing weird issues making precise curves with p5.plotSVG in p5.js 2.0, I recommend using the "1.x compatibility add-on for shapes", located here,
https://github.com/processing/p5.js-compatibility/blob/main/src/shapes.js, and discussed here: https://github.com/processing/p5.js-compatibility
