Bug 159930 [Dialogs] Remove the ControlAnimator from the Preferences and TitleArea dialog
M2 We have decided to remove the control animations. We are also going to remove the background colors from the error message and keep them as the same as the plain message background.

	 * <p>
	 * Note that for backward compatibility, a message of type
	 * <code>ERROR</code> is different than an error message (set using
	 * <code>setErrorMessage</code>). An error message overrides the current
	 * message until the error message is cleared. This method replaces the
	 * current message and does not affect the error message.
	 * </p>
	 * 
	 * @param newMessage
	 *            the message, or <code>null</code> to clear the message
	 * @param newType
	 *            the message type
	 * @since 2.0
