Title: Position option to attach tooltips to fixed elements

I was searching for a simple way to attach fixed tooltips to fixed elements. So I decided to adapt the sources to add this feature.

I hope it will interest you and someone will review and merge it. I think it will be useful for other people !

Thanks !
