I hope this isn't a question that's been answered a thousand times, but
I've read the documentation up and down and it doesn't give me a clue as
to what's going on...

While attempting to write some code to read primitives from an already
linked TMD model (for the purpose of using its polys for collision
detection) I discovered that GsLinkObject4 is tinkering with the first
primitive in the object: Specifically it writes over the first
primitive's ilen and olen with "0x0400".

Without the ilen it's a bit trickier to write a good routine to read the
polys out of the primitives :P I assume that this is some kind of
marker/counter that an object has been linked to a GsDOBJ2, but it's
annoying!

I can easily work around this problem (in this particular model every
primitive has the same length), but I'd still like to know what's going
on! (And maybe suggestions as to what I could be doing better :)

Thanks for the help! (Or as more frequently is the case, pointing out
why I shouldn't be asking this question in the first place. ;)
