Well, no one answered this back in August, and now I have the same
problem with another figure.
Again, is there some way to position several lines of text within
a plot written at different cex sizes so that the relative spacing of
the lines remains fixed when the plot is resized or written to
a device?
That is, I'd like to have such caption text treated as a fixed block
which, under rescaling would expand contract uniformly.
