Ok.

The problem is, you have to utilize the font metric to get the width
information for strings in PDF. So anything besides left-aligned is
non-trivial. But it is hope in the long run. I have to deal at this
moment with fonts in PDF. It might be, that I can reuse some code in the
future in gl2ps.

I don't see any serious problem here. Yes, we could remove it.

Good night from Europe |-)
