[PD] GEM/math: correctly rotating in space

[cyrille henry]

hello,

your right, tLink3D does not do this, as i thought.
i should fix it....
tLink2D does, but it's easy.

i've got an other patch that is doing this (with only 1 moving point : 
changing to your nead will be easy i think)


hope it will halp.

Cyrille
