	 * Constructor for a new <code>Avatar</code>.
	 *
	 * @param {string} [sId] ID for the new control, generated automatically if no ID is given
	 * @param {object} [mSettings] Initial settings for the new control
	 *
	 * @class
	 * An image-like control that has different display options for representing images, initials,
	 * and icons.
	 *
	 * <h3>Overview</h3>
	 *
	 * The <code>Avatar</code> control allows the usage of different content, shapes, and sizes
	 * depending on the use case.
	 *
	 * The content types that can be displayed are either images, icons, or initials. The shape
	 * can be circular or square. There are several predefined sizes, as well as an option to
	 * set a custom size.
	 *
	 * <h3>Usage</h3>
	 *
	 * Up to three Latin letters can be displayed as initials in an <code>Avatar</code>. If there
	 * are more than three letters, or if there's a non-Latin character present, a default image
	 * placeholder will be created.
	 *
	 * There are two options for how the displayed image can fit inside the
	 * available area:
	 * <ul>
	 * <li>Cover - the image is scaled to cover all of the available area</li>
	 * <li>Contain - the image is scaled as large as possible while both
	 * its height and width fit inside the avalable area</li>
	 * </ul>
	 * <b>Note:</b> To set a custom size for the <code>Avatar</code>, you have to choose the <code>Custom</code>
	 * value for the <code>displaySize</code> property. Then, you have to set both the
	 * <code>customDisplaySize</code> and <code>customFontSize</code> properties.
