[Bf-animsys] Collada Importer still broken for Characters with multiple meshes/bind poses.

As far as i can tell the Collada Importer was originally created for 
import of
single animated mesh objects. This is doubtless a limitation. I have 
looked into
this a while back and i got the impression that adding this feature would
result in a major rewrite of the Collada Importer. And since we always 
to "keep symmetry" (also be able to export multiple animated objects)
the exporter would need to be rewritten in some major parts as well.

I did not dare to start such a large change all on my own when i first 
at it. And now since we are about to get full FBX support i have the 
impression that working on the Collada module has become more or less
obsolete and a waste of time.

Please correct me if i am wrong with any point. If anybody thinks this 
can be
done with reasonable effort, then please provide a patch for it. And keep
available for a while while i take care to add that patch to the source.

Sorry if that is not a convenient answer, but that is all that i personally
can offer for now.


p.s.: My personal opinion is that i think Collada is a good thing, 
because it
is an open format. But it also has proven to be a complex beast and getting
it to work in a convenient way for everybody needs quiet some extra power
on the developer side which never existed since i stepped in. So i could get
it to work for the Second Life people, no more no less.
