Thanks.  Somehow the answer of Martin Simmons from LispWorks doesn't
show up on gmane.org so instead of providing a URL I include it here.
I don't think this is something I can change from within my
application.

Cheers,

It looks to me like there is a problem with the font scaler on that machine.
Looking at one of the names xlsfonts returned:

-misc-fixed-medium-r-normal--14-110-100-100-c-70-iso8859-1

we see that the 14 is the pixel-size, the 110 is the point-size times 10 and
the 100-100 is the x-y resolution in pixels/inch.  However, since 1 point is
1/72 inch, we should have the identity:

point-size = 72 x pixel-size / resolution

This computes point-size = 10.08, so point-size times 10 should be 101, not
110!  There is a similar inaccuracy with the other fonts listed.  In fact, all
the "point-size times 10" values are multiples of 10, it looks to me like it
is rounding too early.
