It seems that vbo_exec_vtx_flush gets called with
exec->vtx.vertex_size=0 and we get a division by zero. Not sure I
understand this, but since this happens when linelist[i][1] = -1 in
wind::update, I thought it was a bit strange that an empty GL_LINES
block is run. This patch seems to avoid the crash at least.
