Unable to Use Custom Fonts Windows 10

## Issue or Feature

I have exhausted every guide on the web. I am currently unable to use any custom font on Windows 10.
Error message: Pango-WARNING **: 12:15:05.151: couldn't load font "Roboto Light Not-Rotated 25px", falling back to "Sans Light Not-Rotated 25px", expect ugly output.

## Steps to Reproduce

```js
var Canvas = require('canvas');
var canvas = Canvas.createCanvas(200, 200);
var ctx = canvas.getContext('2d');
Canvas.registerFont('src/fonts/Roboto-Light.ttf', { family: 'Roboto-Light' });
ctx.font = '25px Roboto-Light';
ctx.fillText('ABC', 0, 0);
// etc.
```
