WebGL2RenderingContext

The WebGL2 rendering context for the screen canvas, backed by a real OpenGL ES 3 context on the Switch GPU. Acquire it with screen.getContext('webgl2').

The screen may only have ONE context kind: once a '2d' context exists, getContext('webgl2') returns null (and vice versa).
