ok, scusate il subject un po' stupido, 
ma ho trovato questo:
http://code.google.com/p/svgfig/

ed è veramente la soluzione definitiva per A4, se funziona ci risolve già da 
solo la metà dei nostri problemi.

In particolare, tratto da questa pagina:
http://code.google.com/p/svgfig/wiki/Version2Announcement
dice:
SVG elements now know how to transform themselves and calculate their bounding 
boxes; this functionality is also defined in defaults.py:

e io dico:
uuuoooooooooohhhh!!!!!

nel frattempo ho preparato un pacchettino (brutto e fatto male, ma 
sfunzionicchia) qui:
http://debomatic.debian.net/unstable/pool/svgfig_2.0.0alpha2-1/

potete installarlo e poi provare il tutorial che trovare sul sito (con qualche 
namespace da cambiare):

In [11]: from svgfig import *

In [12]: s = SVG("rect", x=10, y=10, width=60, height=60)
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

/home/gaspa/<ipython console> in <module>()

NameError: name 'SVG' is not defined

In [13]: s = svg.SVG("rect", x=10, y=10, width=60, height=60)

In [14]: print s.xml()
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd";>

    <rect x="10" y="10" width="60" height="60" stroke="black" fill="none" />
</svg>

Yeah.

Invece purtroppo non gli piacciono i nostri svg (e non ho ancora capito 
perchè):

In [16]: 
svg.load('/home/gaspa/Projects/a4/trunk/tests/images/A4_nested_transforms.svg')

ma la 'x' c'è... bohhh...

ok, basta, mi ritraggo nei miei meandri (e preparo l'ITP per farlo inserire il 
prima possibile in debian/ubuntu) \o/

byebye!
