Using proportional fonts on the mode line will cause annoying
horizontal shifts when, say, "--" is replaced with "**" or ""%%" is
replaced with "%*", or when the line number changes or the time shown
in the mode line changes.  So if we want to use such fonts there and
avoid such shifts, we will need to treat the mode line as a kind of
table, where each part starts at a horizontal position that is aligned
at pixelwise resolution.  We'll probably need to see what this means
for the current implementation of mode-line display, especially with
those :eval parts.
