/**
 * @ngdoc directive
 * @name ionContent
 * @module ionic
 * @delegate ionic.service:$ionicScrollDelegate
 * @restrict E
 *
 * @description
 * The ionContent directive provides an easy to use content area that can be configured
 * to use Ionic's custom Scroll View, or the built in overflow scrolling of the browser.
 *
 * While we recommend using the custom Scroll features in Ionic in most cases, sometimes
 * (for performance reasons) only the browser's native overflow scrolling will suffice,
 * and so we've made it easy to toggle between the Ionic scroll implementation and
 * overflow scrolling.
 *
 * You can implement pull-to-refresh with the {@link ionic.directive:ionRefresher}
 * directive, and infinite scrolling with the {@link ionic.directive:ionInfiniteScroll}
 * directive.
 *
 * Be aware that this directive gets its own child scope. If you do not understand why this
 * is important, you can read [https://docs.angularjs.org/guide/scope](https://docs.angularjs.org/guide/scope).
 *
 * @param {string=} delegate-handle The handle used to identify this scrollView
 * with {@link ionic.service:$ionicScrollDelegate}.
 * @param {string=} direction Which way to scroll. 'x' or 'y' or 'xy'. Default 'y'.
 * @param {boolean=} locking Whether to lock scrolling in one direction at a time. Useful to set to false when zoomed in or scrolling in two directions. Default true.
 * @param {boolean=} padding Whether to add padding to the content.
 * of the content.  Defaults to true on iOS, false on Android.
 * @param {boolean=} scroll Whether to allow scrolling of content.  Defaults to true.
 * @param {boolean=} overflow-scroll Whether to use overflow-scrolling instead of
 * Ionic scroll.
 * @param {boolean=} scrollbar-x Whether to show the horizontal scrollbar. Default true.
 * @param {boolean=} scrollbar-y Whether to show the vertical scrollbar. Default true.
 * @param {string=} start-y Initial vertical scroll position. Default 0.
 * of the content.  Defaults to true on iOS, false on Android.
 * @param {expression=} on-scroll Expression to evaluate when the content is scrolled.
 * @param {expression=} on-scroll-complete Expression to evaluate when a scroll action completes.
 * @param {boolean=} has-bouncing Whether to allow scrolling to bounce past the edges
 * of the content.  Defaults to true on iOS, false on Android.
