it is not really important for me it is just a open point on my list. I 
wanted to get rid off this hack in RenderAction::draw()

// ok for cgfx I have to call it also for equal states
// to update the world matrix.
if(pRoot->isMultiPass() || pRoot->isNoStateSorting() ||
    pNewState != _pActiveState)
{
     pNewState->changeFrom(this, _pActiveState);
}
