Comment 23 for bug 1240455

the files hershey.py, polyhedron_3d.py, render_barcode.py, render_barcode_datamatrix.py, render_barcode_qrcode.py, have been updated in rev 13015 to deal with scaling problems. The approach taken was to apply a transform to the group that contains the newly rendered object.

I will look at one more Render item, namely Grids->Grid, which is an internal extension.
