+ * The properties of a device are:
+ * - name: brand and model(s).
+ * - width: viewport width.
+ * - height: viewport height.
+ * - pixelRatio: ratio from viewport to physical screen pixels.
+ * - userAgent: UA string of the device's browser.
+ * - touch: whether it has a touch screen.
+ * - firefoxOS: whether Firefox OS is supported.
+ *
+ * The device types are:

+ *
+ * You can easily add more devices to this catalog from your own code (e.g. an

+ *
+ *   var myPhone = { name: "My Phone", ... };
+ *   require("devtools/client/shared/devices").addDevice(myPhone, "phones");
