/**
* @class vtkOpenGLPropItem
* @brief Sync Context2D state with vtk camera.
*
*
* 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.
