Uhm, no. Or it might, but since I can't make out any of the text, I
can't tell :) Other downsides apart from the unreadable text is that
the 1.3beta generates much larger SVGs that really bog down Firefox,
both filesize and when rendered by Firefox. I put up a pair of examples,
both generated with the rrdcgi script below.
http://www.modeemi.fi/~as/ctxt_new.svg was generated by 1.3beta,
http://www.modeemi.fi/~as/ctxt_old.svg was generated by 1.2.15.
The filesize increase in this one is huge, over 10x. I notice there are
no text elements in the SVG generated by 1.3beta.
/var/www/ctxt.svg -t "Number of CPU context switches (Dorkstar)" -v
"Context switches per second"
--imgformat SVG --imginfo ""
--width 1000 --height 250
--units-exponent 0 --y-grid 500:1
LINE2:ctxt#1BC100:"Number of CPU context switches"
