// .NAME vtkChooserPainter - Painter that selects painters to render
// primitives.
//
// .SECTION Description
//
// This painter does not actually do any painting. Instead, it picks other
// painters based on the current state of itself and its poly data. It then
// delegates the work to these other painters.
