To find the relevant changes I have verified that the numbers increased
by the factor of 2048 divided by the old Em size (11 or 13 or 15). Of
course as 11, 13, 15 aren't factors of 2048 there are rounding errors.

But it doesn't matter as:
a) Those are bitmap only fonts.
b) Only the *.fon files are installed but not the corresponding *.ttf files.
c) The generated *.fon files are bit by bit identical (sha1sum) before
and after this commit.
