These are quite cool already. :-)

This reverts commit 30ae981c.
Was actually already there!

The zoom focus discussion on IRC suggests that everybody is annoyed
about centering behavior (or lack thereof), so here is a way to
explicitly center the image witout zooming.

... _even at low zoom levels_

Pass GIMP_ZOOM_FOCUS_POINTER to gimp_display_shell_scale() when
wheel-scrolling, and change the scaling code to really honor
GIMP_ZOOM_FOCUS_POINTER and not apply magic image centering.

This keep the same point centered under the mouse for wheel-scrolling
and the zoom tool (== when the zooming is really triggered at a
certain mouse position).

Forgot to do this for 2.10.0.

Also fix a typo.

See commit ea3de6d5.
Also update the translation list in NEWS.
