| The Font Software may not be modified or altered in any way, except
| that: (a) the Fonts may be converted from one format to another
| (e.g., from TrueType to Postscript), in which case the normal and
| reasonable distortion that occurs during such conversion shall be

| the Fonts, so long as the base set of glyphs is not modified or
| removed.

Clearly non-free.

I can understand why people think that such a clause is a technical
necessity (reproducible layout), but it still violates DFSG clause 3.
