+ * requestAnimationFrame
+ *
+ * This is used throughout the BB10 File implementation to wrap
+ * native webkit calls. There is a bug in the webkit implementation
+ * which causes callbacks to never return when multiple file system
+ * APIs are called in sequence. This should also make the UI more
+ * responsive during file operations.
+ *
+ * Supported on BB10 OS > 10.1
