// .NAME vtkOpenGLPropItem - Sync Context2D state with vtk camera.
//
// .SECTION Description
// The vtkContext2D framework modifies the GL state directly, while some actors
// and mappers rely on the modelview/projection matrices from vtkCamera. This
// class is a layer between the two that updates the camera with the current
// OpenGL state.
