[PD] Geo absolute position

[nosehair911 at bellsouth.net]

I have been looking for this answer for a while now.  In Gem, is there a way to get the absolute 
position of a geo after its been rotated, moved, rotated again, etc...?
For example:

[gemhead]
|
[translateXYZ 0 1 0]
|
[rotateXYZ 0 0 90]
|
[translateXYZ 1 0 0]
|
[circle 0.1]
|
[absolute position]

Any workaround or the likes? It would need this information to feed it to pmpd.
Thanks,
Alain
