Yes, exactly the same, except for the font.

Note that Fedora has TT_CONFIG_OPTION_BYTECODE_INTERPRETER disabled because of
patents treats (while it is activated in Debian and Gentoo, for example).

This prevents the hinting bytecode interpreter to work, and changes the
rendering and size quite a bit. However, I only get enabling compatible size
when the hinting bytecode interpreter is enabled: under Fedora I couldn't get
the same text size than under Windows for the game engine.

I attach 2 screenshots, showing FreeType's 'ftview' utility with size 16 and
anti-aliasing disabled (what the game uses). Left is 1.03, right is 1.04. The
first screenshot has glyph hinting on, the second has it off.

On the first one you'll see the difference on "y".

This could mean that the hinting bytecode was not or not properly imported in
fontforge, which would be embarrassing.

Indeed 1.03 doesn't present this issue.
