Subject: experimental: do not auto allocate a skeletonobject when a CSQC model just uses frame... 
X-Git-Tag: xonotic-v0.1.0preview~103
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=9e7c3b0a5a7cdd82bf932cc803552678b4a9d05e;p=xonotic%2Fdarkplaces.git

experimental: do not auto allocate a skeletonobject when a CSQC model just uses frame based animation (NOTE: this MAY even cause crashes, please test, I just can't find any case where that object is really required); this moves blending of frame based animations back into Mod_Skeletal_AnimateVertices again (if this commit causes worse performance, a different course of action may be reverting it, and making sure a skeletonobject is ALWAYS created, even for SVQC managed legacy entities)
