* @class vtkTextSource
* @brief create polygonal text
*
* vtkTextSource converts a text string into polygons. This way you can
* insert text into your renderings. It uses the 9x15 font from X Windows.
* You can specify if you want the background to be drawn or not. The
* characters are formed by scan converting the raster font into
* quadrilaterals. Colors are assigned to the letters using scalar data.
* To set the color of the characters with the source's actor property, set
* BackingOff on the text source and ScalarVisibilityOff on the associated
* vtkPolyDataMapper. Then, the color can be set using the associated actor's
* property.
*
* vtkVectorText generates higher quality polygonal representations of
* characters.
