Motivation is to resolve DirectGraphPlugin's conflict issue with other plugins. When viewing a page with a DirectGraphPlugin, DirectGraphPlugin's commonTagHandler invokes "TWiki::Store::saveAttachment" to attach generated image files to a topic, which triggers "beforeAttachmentSaveHandler" and "afterAttachmentSaveHandler". This might cause conflicts with plugins which handle "beforeAttachmentSaveHandler" and "afterAttachmentSaveHandler". To resolve this problem, DirectGraphPlugin should give a way to skip dispatching messages.
