 The entry point to most WebGL code is through **p5.RendererGL**. Top-level p5.js functions are passed to the current renderer. Both 2D and WebGL modes have renderer classes that conform to a common `p5.Renderer` interface. Immediate mode and retained mode functions are split up into `p5.RendererGL.Immediate.js` and `p5.RendererGL.Retained.js`.
