Likely `bool GraphicsLayerTextureMapper::addAnimation(const KeyframeValueList& valueList, const GraphicsLayerAnimation* anim, const String& keyframesName, double timeOffset)` needs to be adapted, to be more like GraphicsLayerCA -- I guess it's related to keyframe construction, and what we end up passing to TextureMapperAnimation, but just a quick guess.
