Newbie Library svg.jar on old Processing 2.1.2

Dear All,

I’m quite new on Processing, I’ve just built a V pen Plotter and I’m Using Processing 2.1.2 in order to run polargraph controller (newer version do not run properly). Now I’m trying another application named SquiggleDraw, but when I try to run I’ve the following exception

No library found for processing.svg
Libraries must be installed in a folder named ‘libraries’ inside the ‘sketchbook’ folder.
Error in contribution listing file on line 1

svg.jar is missing, after a research I understood that on newer Processing version this library is deprecated, but I’m not able to find it elsewhere, is still available for download?

How can I solve?

May I install latest Processing Version 4.4.1 and run both?

Thanks in Advance
