I'm a bit concerned that changing from an even to an odd row height may case our
(centered) svg icons to render on half-pixel alignment and look fuzzy/blurry. If
the row icons (such as content-settings) look the same then this may not be an
issue. Do they look ok?

Just checked on Mac and Goobuntu, on both machines they icon looks the same for
44px and 45px line-heights, so I think they'll look okay.
