SetNextWindowPos: added a ImVec2 pivot parameter for positioning a given a center, bottom-right position, etc. As a generalization of SetNextWindowPosCenter() which is now obsolete. This will be useful for combo-like popups as well.

Demo: Simple-overlay window uses the SetWindowPos pivot to select a corner to position itself at.
