Yesterday, 13 March 2003, I wrote as follows.
So I reasoned that the system might scan through a font when it is loaded
and decide upon the lowest point for the whole font and then proceed on that
An email correspondent has kindly written to me privately and I now know
that it is not necessary for an application such as a wordprocessing package
to make a complete survey of all the glyphs in a font as the font is being
loaded, because the information on what are the high and low points for the
font is readily available in predefined locations within the font.
I expect that many readers of this list already know that, yet I feel that I
should post this note in case some readers do not because I would not want
to have set them off on a wrong way of looking at how a system works.
