If @var{position} is visible, @code{pos-visible-in-window-p} returns
@code{t} if @var{partially} is @code{nil}; if @var{partially} is
non-@code{nil}, it returns a list of the form @code{(@var{x} @var{y}

relative to the top left corner of the window, and @var{partial} is
@code{nil} if the character after @var{position} is fully visible;
otherwise it is a cons @code{(@var{rtop} . @var{rbot})} where the

non-@code{nil}, and the character after @var{position} is fully
visible, it returns a list of the form @code{(@var{x} @var{y})}, where
@var{x} and @var{y} are the pixel coordinates relative to the top left
corner of the window; otherwise it returns an extended list of the
form @code{(@var{x} @var{y} @var{rtop} @var{rbot} @var{rowh}

of invisible pixels at the top and bottom of the row at
@var{position}, @var{rowh} specifies the visible height of that row,
and @var{vpos} specifies the vertical position (zero-based row number)
of that row.
Here is an example:
