This is the tagged protocol for use over the toGraphics configuration channel of an active graphics component.
It is a collection of static immutable enquiry/configuration objects and static configuration classes. An enquiry sent down the toGraphics channel generates an appropriate reply on the fromGraphics channel. A configuration class may be used to construct an immutable configuration object that may be sent down the toGraphics channel to configure some property of the graphics component. A configuration message is always acknowledged with a Boolean.TRUE returned on the fromGraphics channel (once the configuration has happened).
