Just to give everyone an update on this plplot-general list about the results of that discussion on plplot-devel, the problem has been almost entirely solved. That solution involved touching a lot of different files, and there are still some minor issues that need to be polished up, but it is clear the next release of Plplot will have floating point line widths. So that is a big improvement on integer line widths, and my thanks to Hǎiliàng for resurrecting the discussion of this old issue and thus inspiring us to make the fix.
