tracks state of background color(s).
vtkBackgroundColorMonitor – A helper for painters that tracks state of background color(s). A Painter could use this to skip expensive processing that is only needed when background color changes. This class queries VTK renderer rather than OpenGL state in order to support VTK's gradient background.
this is not intended to be shared. each object should use it's own instance of this class. it's intended to be called once per render.
