// .NAME vtkVBOLinesPainter - this painter paints triangle strips using vertex
// buffer objects to increase data transfer speeds.
// .SECTION Description
// This painter tries to paint triangle strips efficiently. Data are
// transfered in bulk to vertex buffer objects and then rendered from
// these buffers. If vertex buffer objects are not supported, or if
// they cannot be allocated, then this renderer cannot render the
// primitive and will propagate the request to the delegate painter.
// Requests to Render any other primitive are ignored and not passed
// to the delegate painter, if any. If this class is able to render
// the primitive, the render request is not propagated to the delegate
// painter. Cell attributes are not supported.
