 - standard globalAlpha and rgba() alpha compositing

 - clip shapes

## Installation

Install with [npm](https://npmjs.org/package/purified-image):

```js

const Image = require('purified-image');

let image = new Image('img/template.png');

image

  .loadFont('/res/OpenSans.ttf')

  .draw(ctx => {

    ctx.fillStyle = '#000000';

    ctx.font = '20 Open Sans';

    ctx.fillText('example', 30, 30);

  })
