P5.js texture() error - Uncaught TypeError: Cannot read property 'width' of undefined

Hi!

I have come across with a problem while practising the following lesson.
https://www.youtube.com/watch?v=O1mYw-3Wl_Q

texture(); function doesn't work for me. I have attached the console log error as well.

```javascript
let visual;

function preLoad(){
visual = loadImage('http://i55.tinypic.com/16axyx0.jpg');
}

function setup(){
createCanvas(windowWidth,windowHeight,WEBGL);
}
function draw(){

ambientLight(0,0,255);

background(51);
noStroke();
//normalMaterial();
//ambientMaterial(255);
rotateX(frameCount*0.01);
rotateY(frameCount*0.01);
rotateZ(frameCount*0.01);
//ellipsoid(width/6);
texture(visual);
box(200,200,200);
}
function windowResized(){
resizeCanvas(windowWidth,windowHeight,WEBGL);
}
```

Thanks in advance.

Start by running the supplied JavaScript sketch with p5.js in WEBGL mode and inspect the console around texture(visual). Read the texture() and image-loading documentation, then verify that the sketch renders the textured box without the reported TypeError.
