Hi Dave:
It renders the text with
plptex( text_x_world + text_justification * text_width0, ty,
0.1, 0.0, text_justification, text[i] );
where i is the index of the entry within the legend. IOW, pllegend
contains a bit of low-level PLplot C library manipulation to determine
ratios of some units with others, save internal PLplot variables for
later restoration, etc., but most of it is high-level, i.e., it simply
makes calls to ordinary PLplot functionality such as plptex to get the
job done.
