// .NAME vtkVectorText - create polygonal text
// .SECTION Description

// vtkVectorText generates vtkPolyData from an input text string. Besides the
// ASCII alphanumeric characters a-z, A-Z, 0-9, vtkVectorText also supports
// ASCII punctuation marks. (The supported ASCII character set are the codes
// (33-126) inclusive.) The only control character supported is the line feed
// character "\n", which advances to a new line.
//
// To use thie class, you normally couple it with a vtkPolyDataMapper and a
// vtkActor. In this case you would use the vtkActor's transformation methods
// to position, orient, and scale the text. You may also wish to use a
// vtkFollower to orient the text so that it always faces the camera.
