  I tried bins (pfDrawBin), without any success. pfDrawBin(MY_BIN) simply draws
nothing (maybe some help ?)
I made something else : it is to disable Zb before drawing a node, then
re-enable it after, all this in per-node draw callbacks. If you don't use any
SORT token in the culling mode, then the drawing process should traverse your
subtree normally, and draw each sub-node one above the previous.
For disabling and enabling Zbuffer, consult the OPEN GL and IRIS GL manuals,
i don't remember the function names, and I don't have my sources in front of
me...
