We seem to be miscommunicating. I'm saying that it seems likely that
people have scripts and things that use the API of the plot library to
build graphs and things in various places. I'm saying that it seems
unlikely that people have programs that depend on a pixel-perfect
rendering. I'm saying that, imo, the best thing we can do for our
users here is provide a compatibility layer for the old plot in the
same place as the old plot currently is that calls into the new plot
and uses it to draw the actual pictures.
