+// testing what types of content it supports.

+// We're using the Boolean constructor here, so that we can extend the value
+// e.g.  Modernizr.audio     // true
+//       Modernizr.video.ogg // 'probably'
+//
+// Codec values from : github.com/NielsLeenheer/html5test/blob/9106a8/index.html#L845

+// Note: in some older browsers, "no" was a return value instead of empty string.
+//   It was live in FF3.5.0 and 3.5.1, but fixed in 3.5.2
+//   It was also live in Safari 4.0.0 - 4.0.4, but fixed in 4.0.5
