[Bf-committers] 2.49: prevent reading 2.5+ ?

[blender at erwincoumans.com]

The new mesh data and animation data is new so not "known data" obviously. 

So the choice of not keeping a copy of the old mesh data is basically giving 
up forward compatibility. That's why I quoted Joe in my previous email. 

I hope Joe can briefly explain why it is impossible to keep a 
copy/conversion between old and new mesh data.
Thanks,
Erwin
