We're setting the width in the CSS, but the new logo has different
proportions than the old one, so a width of 200 is still leaving
the logo a bit tall. Switch to setting height, (which was coming out
to 51.4 with a width of 200) and shrink it a bit to make it better
match the rest of the top title bar.
