Font-Size different (LARGE) in Azure Web App

When I deploy a working example to my Azure Web App instance the font-size at 14px is GIGANTIC (like 100x). I have to set the font size to 1px to be able to see more than part of one letter.

Any idea what causes this inconsistency between environments? They are both:

- Windows 64-bit
- Node 6.9.1 (64-bit)
- Canvas 1.6.2
- Prebuilt canvas.node (in git repo)

### Examples

**Working Localhost (Size 20px Font)**

**Busted Azure Web App (Size 1px Font)**

## Steps to Reproduce

```js
var Canvas = require('canvas');
var canvas = new Canvas(400,100);
var ctx = canvas.getContext('2d');

const fontSize = process.env.FONT_SIZE || '20';

ctx.fillStyle = 'black';
ctx.font = `${fontSize}px Calibri`;
ctx.fillText("Hello World", 105, 30);
```
