In the release notes I said that there was a problem with the character
positioning when displaying X Window fonts. The following patch appears to
fix this. I have also put the patch on our ftp area, in a separate file.

There is a second problem with the X Window fonts. The problem is that the
encoding of the X Window fonts is not the same as the encoding of the
postscript fonts. Furthermore, there are characters in the postscript fonts
that are not in the X Window fonts and vice versa. What would be a good way
of dealing with this?
