Item7271: DirectedGraphPlugin doesn't support saving images without triggering attachmentSaveHandler

Item Form Data

AppliesTo:	Component:	Priority:	CurrentState:	WaitingFor:	TargetRelease	ReleasedIn
Extension	DirectedGraphPlugin	Low	Closed		n/a

Detail

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.
