Emacs text cursor position

[AM]

I'm trying to customize Emacs to my needs/wants and so far so good.
The only snag I encountered is in the position of the cursor. I want
to be able to to scroll the  buffer with mouse wheel or on the scroll
bars and have the cursor remain on the original line, even if the
cursor moves off-screen. Then when I start typing, emacs does C-l to
center back on the cursor, if the cursor is off-screen.

Is it possible to customize Emacs in this way? How can I set "mouse
scroll" not to affect the position of the cursor?

Thanks,
Adam
