/**
    * Determines if a list or gallery view item should delay loading a url resource because the view is scrolling very fast.
    * The primary purpose of this method is to skip loading remote resources (such as images) over the internet
    * until the list stop flinging and the user is focusing on the displaying items.
    *
    * If the scrolling stops and there are delayed items displaying, the getView method will be called again to force
    * the delayed items to be redrawn. During redraw, this method will always return false, thus allowing a particular
    * resource to be loaded.
    *
    * Designed to be used inside getView(int position, View convertView, ViewGroup parent) of an adapter.
    *
    * <br>
    * <br>
    * Example usage:
    * <pre>
    *              public View getView(int position, View convertView, ViewGroup parent) {
    *                      ...
    *
    *                      if(aq.shouldDelay(position, convertView, parent, tbUrl)){
    *                              aq.id(R.id.tb).image(placeholder);
    *                      }else{
    *                              aq.id(R.id.tb).image(tbUrl, true, true, 0, 0, placeholder, 0, 0);
    *                      }
    *
    *                      ...
    *              }
    * </pre>
    *
    * <br>
    * NOTE:
    *
    * <br>
    * This method uses the setOnScrollListener() method and will override any previously non-aquery assigned scroll listener.
    * If a scrolled listener is required, use the aquery method scrolled(OnScrollListener listener) to set the listener
    * instead of directly calling setOnScrollListener().
    *
    * @param position the position of the item
    * @param convertView the list item view
    * @param parent the parent input of getView
    * @param url the content url to be checked if cached and is available immediately
    *
    * @return delay should delay loading a particular resource
