// .NAME vtkTextSourceRepresentation
// .SECTION Description
// vtkTextSourceRepresentation is a representation to show text. The input is
// expected to a vtkTable with a single row and column (atleast on the data
// server nodes). The content of this entry in the table is shown as text on the
// rendering nodes.
