<!--
Show image as background to text. You can't really calculate the width
reliably in JS because margins are not taken into account by any of
clientWidth, offsetWidth or scrollWidth, so we don't force a minimum
width if the user is using shrink to fit.
This results in a margin-width's worth of pixels being cropped. If the
user is not using shrink to fit then we expand the header.
