[PD] fftease 3.0 compatibility with Linux. Was Re: fftease compatibility with Pd-0.46-7

Regarding gui slowness, this is because in PD-l2ork the entire canvas is
drawn using SVG shapes and hence the slowdown. As we migrate on to our new
renderer thanks to Jonathan's hard work, things should get exponentially
faster.
