Comment 17 for bug 1240455

the files grid_cartesian.py, grid_isometric.py, grid_polar.py, guides_creator.py, lindenmayer.py, rtree.py, spirograph.py, triangle.py, wireframe_sphere.py, have been updated in rev 13007 to deal with scaling problems. The approach taken was the same as the previous comment

further changes will be made during the next week, focussing only on the Render submenu.
