[osg-users] Updating multiple times references to AnimatioPaths

Hi Alberto,

There isn't lazy updating of the control point in
AnimationPathCallback, as you've found it'll compute the control point
on demand.  Attach a single callback to many nodes is not typical
practice so such a lazy updating technique wouldn't be critical to
most.  It'd be easy to add though by just modifying the
AnimationPathCallback::update(Node& node) method to something like:

void AnimationPathCallback::update(osg::Node& node)
    if (_cpCacheTime!=getAnimationTime())
         _cpCacheTime =getAnimationTime();

    AnimationPathCallbackVisitor apcv(_cpCached,_pivotPoint,_useInverseMatrix);

Feel free to code such a change, and if it works out fine for you to
submit it to osg-submissions.
