Comment 4 for bug 895030

Not sure how that would work, arbitrarily deciding the owner at design time makes no sense to me. You need a way to specify 'invoker' or 'neutral'.
The only special case I can think of is DeathAnim where you need to be able to specify 'original owner', 'neutral' or 'killer'

This could be simplified to just have an enumerated flag (like category/armor) on the animation:
MakeInfantryOwner=normal/neutral/inverse
For normal (default), whichever player invoked the anim
For InfDeaths, normal = killer, inverse = killed
For DeathAnims, normal = dying, inverse = killer
