/**
 * @class   vtkVectorText
 * @brief   create polygonal text
 *
 *
 * 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 this 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.
