I didn't explain that well enough: I don't mind if the size in one system
isn't the same as the size in another system, what I want is to make sure
there are no gaps between two rows of characters.
Currently, in my Windows system the height is reported to be 27 and the
characters are (apparently) drawn to be 27 pixels high, which is good, but
in my Linux system the height is reported to be 28 and the characters are
(apparently) NOT 28 pixels high, which is a problem.

The font is installed in both systems and I also did a binary comparison
between their font files. They're identical.
