org.eclipse.jface.text.source.projection.ProjectionViewer
A projection source viewer is a source viewer which supports multiple visible regions which can dynamically be changed.
A projection source viewer uses a ProjectionDocumentManager for the management of the visible document.

NOTE: The ProjectionViewer only supports projections that cover full lines.

This class should not be subclassed.
@since 3.0 @noextend This class is not intended to be subclassed by clients.
