'LineToElement' may be skipped if it doesn't move the center point of the line. We should make sure that we don't end up with a lost 'MoveToElement' in the vertex buffer, not connected to anything. Since the buffer uses degenerate triangles trick to split the primitives, this spurious MoveToElement will create artifacts when rendering.
