// will show an icon, @title (in bold) and @banner, all on a single
// line (with @banner ellipsized if necessary).
//
// The notification will be expandable if either it has additional
// elements that were added to it or if the @banner text did not
// fit fully in the banner mode. When the notification is expanded,
// the @banner text from the top line is always removed. The complete
// @banner text is added as the first element in the content section,
// unless 'customContent' parameter with the value 'true' is specified
// in @params.
//
// Additional notification content can be added with addActor() and
// addBody() methods. The notification content is put inside a
// scrollview, so if it gets too tall, the notification will scroll
// rather than continue to grow. In addition to this main content
// area, there is also a single-row action area, which is not
// scrolled and can contain a single actor. The action area can
// be set by calling setActionArea() method. There is also a
// convenience method addButton() for adding a button to the action
// area.
//
// @params can contain values for 'customContent', 'body', 'icon',
// 'titleMarkup', 'bannerMarkup', 'bodyMarkup', and 'clear'
// parameters.
//
// If @params contains a 'customContent' parameter with the value %true,
// then @banner will not be shown in the body of the notification when the
// notification is expanded and calls to update() will not clear the content
// unless 'clear' parameter with value %true is explicitly specified.
//
// If @params contains a 'body' parameter, then that text will be added to
// the content area (as with addBody()).
//
// By default, the icon shown is created by calling
// source.createNotificationIcon(). However, if @params contains an 'icon'
// parameter, the passed in icon will be used.
//
// If @params contains a 'titleMarkup', 'bannerMarkup', or
// 'bodyMarkup' parameter with the value %true, then the corresponding
// element is assumed to use pango markup. If the parameter is not
// present for an element, then anything that looks like markup in
// that element will appear literally in the output.
//
// If @params contains a 'clear' parameter with the value %true, then
// the content and the action area of the notification will be cleared.
// The content area is also always cleared if 'customContent' is false
// because it might contain the @banner that didn't fit in the banner mode.
