Thanks for making this change happen! I tested locally, looks good!

Oh, the tests caught something I didn't test: drawing an image using image() now adds lines. Demo here, try toggling which p5 import in index.html is commented to see how p5 1.5.0 behaves: https://editor.p5js.org/davepagurek/sketches/nbzbYeVbp

I think we probably just need to call noStroke() in the WebGL implementation of image(): https://github.com/processing/p5.js/blob/main/src/webgl/3d_primitives.js#L1998

Right now the tests are still failing, I believe it's because we can't call the global noStroke() here in case p5 is running in instance mode. I think calling this._pInst.noStroke() should fix it though!

Awesome, thanks for making those changes!
