The name alone might suggest that, but the code tells a different
story.  I thought you looked in the code and saw there something I
missed, thus my questions.

I did strive, as "git log" will show.  That's the best I could come up
with, without complicating this stuff even more.  IMO, it's not that
bad, so "should not be used for line numbers" sounds a bit radical to
me.

You forgot tooltips and the font used for the caption bar.

It's not a bug, since the code was written to produce that effect.  (I
think similar issue happens in the NS build.)
