Here's the doc string. There is nothing here that tells you the X is
across the screen (horizontal) and Y is down the screen
(vertical). All it says is that X,Y=0,0 is at the top left.
Yes, you can look up other doc to find out what is meant by position
and character cell, but this explanation might as well be
self-contained.
Return a list (FRAME X . Y) giving the current mouse frame and position.
The position is given in character cells, where (0, 0) is the
upper-left corner.
If Emacs is running on a mouseless terminal or hasn't been programmed
to read the mouse position, it returns the selected frame for FRAME
and nil for X and Y.
If `mouse-position-function' is non-nil, `mouse-position' calls it,
passing the normal return value to that function as an argument,
and returns whatever that function returns.
