For example, when we draw the mode-line of a window: Do we first clip
the glyphs on the bottom of the last proper line of the window or do we
draw them unclipped and afterwards draw the mode-line on top of it so it
obscures the lower part of the window line?

Yes. So the event reporting mechanism fully supports windows that
display partially visible lines.

Let's say the TTY equivalent of the upper window would display 5 lines.

In this case the TTY equivalent would display (6, 5) lines.

Currently it loops calling `pos-visible-in-window-p' until the position
is visible. How avoid that loop?
