Doug,
Thanks for your code but I think you misanderstood the rotation
I am interested in.
I will try to explain with another draw.
CR1 CR2
X----------------0----------------
L1 L2
L1 is rotated around CR1,
L2 is rotated around CR2,
CR2 is rotated around CR1
This to understand how we represent absolute, relative
cs with SVG.
If you have idea..
Thanks a lot,
Jilu
