I can reproduce the problem here (with 3.37), but I don't know why it
occurs (well, presumably because the `@Graphic' object doesn't have a
zero width, for some reason).

You can work around it by adding "|0co" right after the "@BackEnd"
block: it tells Lout to concatenate the next object (i.e., "Line 1")
such that it over-strikes the `@Graphic' object horizontally (see the
Expert's Guide for details).

BTW, in 3.37, you can use `@DocInfo' instead of the whole `@BackEnd'
thing; it has the same problem, though.

Thanks,
