Description of the change

This is a 2 line hack to fix bug 898797 "Bend LPE incorrect on groups with objects which have a preserved transformation.

It applies the transformation of the subitem relative to the group to the curve before applying the effect, and then it's inverse to remove it from the output curve.

Please note that I'm not confident that it is the best solution and dont know whether someone else has been working on this. It just works for my test cases.

Thanks Adonis
