Interface: WebGLContextConstructor<T>

Defined in: types/desktop-engine.d.ts:3324

The global WebGLRenderingContext / WebGL2RenderingContext (also on DesktopEngine), set up by the Canvas module polyfill. Stand-in classes for instanceof and gl.constructor.name (the contexts are native objects); they hold no constants. instanceof compares Object.prototype.toString tags, so a WebGL 2 context is not instanceof WebGLRenderingContext (the same as in browsers, where WebGL2RenderingContext doesn't inherit WebGLRenderingContext); check for WebGL 2 first, since the types make WebGL2RenderingContext extend WebGLRenderingContext and narrow the else branch to never.
