The Emacs display engine is based on the principle that point should always be visible, so whenever it becomes invisible, Emacs scrolls the window to make it visible again. The display code checks this in many places, and they all will need to be changed in some, yet unspecified, way. Emacs provides the mark and "C-x C-x" as a way to jump between two locations without requiring the feature you describe. If the purpose of what you want is some other use case, I think it would be good to have it described.
