Follow-up Comment #9, bug #34146 (project octave):

I have confirmed that gnuplot has changed the way SVG is output. The code
snippet below is from their developer's cvs.

    if (SVG_fixed_size)
        fprintf (gpoutfile, "n width="%u" height="%u" ",
                 (unsigned int) (term->xmax / SVG_SCALE),
                 (unsigned int) (term->ymax / SVG_SCALE));

    fprintf (gpoutfile, "n viewBox="0 0 %u %u"n",
             (unsigned int) (term->xmax / SVG_SCALE),
             (unsigned int) (term->ymax / SVG_SCALE));

The current sources should produce an unscaled version by default. Ironically,
the manual for the 4.4 series indicates that unscaled is the default, but
gnuplot produces a scalable version, none the less.

In any event, the sources can be modified to ensure the output is scalable for

As we'd like the OpenGL output to be consistent, I'll check with the glps
developers to see what can be done there.
