Font Format Feature Detection

This library detects support for @font-face font formats without resorting to user agent sniffing. To do this efficiently, it makes the following assumptions:

• All browsers support OpenType fonts (except IE6-8).
• All browsers that support WOFF2 support WOFF.
• All browsers that support WOFF support OpenType.

Usage

var fontformat = new FontFormat();

fontformat.detect().then(function (formats) {
  // formats = ['opentype', 'woff', 'woff2']
});
