(By way of further explanation, the project this arises in involves
a set of

separate program. I would like the lineWidth and other drawing

reusable
paths are drawn, rather than a property of the paths themselves).
I don't think that's going to work.
My take on what +setDefaultLineWidth: means is that this establishes
the value for a path's -lineWidth when it is first created. From that
instant on, the path itself has a defined line width, a copy of the
default value. If you never set the default I believe it defaults to
1.0.
When you dearchive the paths the line width of each will be whatever
is recorded for them, which came from the default on the source
machine at the time they were created. Changing the default line width
on your machine will have no effect on these values.
If you want to change the line width when the paths are drawn, you'll
have to set each one individually prior to drawing.
