48 * tnl: If true, line stipple emulation will reset the pattern walker.
49 * vbo: If false and the primitive is a line loop, the first vertex is
50 * the beginning of the line loop and it won't be drawn.
51 * Instead, it will be moved to the end.
56 * tnl: If true and the primitive is a line loop, it will be closed.
