Compute the 4 vertices `a`,`b`,`c`,`d` absolute coordinates of **any**, deep, `transform`ed, `position`ed DOM element.

```
a                b
 +--------------+
 |              |
 |      el      |
 |              |
 +--------------+
d                c
```

# Usage

```js
var el = document.getElementById('foo');

var v = domvertices(el);

console.log(v);
```

outputs:

```js
{
	a: {x: , y: , z: },
	b: {x: , y: , z: },
	c: {x: , y: , z: },
	d: {x: , y: , z: }
}
```

## jQuery plugin

```js
var $el = $('#foo');
var v = $el.domvertices();

console.log(v);
```

you can also `trace` vertices for debug purpose:

```js
v.update().trace();
```

or remove the trace:

```js
v.erase();
```
