Errors and Device Loss

WebGL reported problems through one sticky gl.getError() code. WebGPU validates every descriptor, binding and pass, and reports through three channels: JavaScript exceptions, error scopes and events for GPU-side validation, and the device.lost promise. Every message below is real output from this book's machine.
