Don't fetch lots of axes state information for rendering if object is not visible.
* gl-render.cc (opengl_renderer::draw_axes_planes): Check axes color and
visibility and return immediately from function if there is nothing to do.
* gl-render.cc (opengl_renderer::draw_axes_boxes): Check axes
visibility and return immediately from function if there is nothing to do.
* gl-render.cc (opengl_renderer::draw_axes_x_grid, drax_axes_y_grid,
draw_axes_z_grid): Check axes state and visibility before bothering to
fetch any more state data.
* gl-render.cc (miscellaneous): Clean up comments. Change lines to wrap at <
80 chars.
* graphics.cc (axes::properties::update_axes_layout): Use std::swap instead
of intermediate temporary variable for clearer coding style.
