// .NAME vtkViewTheme - Sets theme colors for a graphical view.
//
// .SECTION Description
// 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.
