 * @class   vtkViewTheme
 * @brief   Sets theme colors for a graphical view.
 *
 *
 * This may be set on any subclass of vtkView.  The view class will attempt
 * to use the values set in the theme to customize the view.  Views will not
 * generally use every aspect of the theme.
 * NOTICE: This class will be deprecated in favor of a more robust
 * solution based on style sheets.  Do not become overly-dependent on the
 * functionality of themes.
