maybe: "that tell the margin kerns..." because it's read-only

maybe we should add

    - fast direct embedding of png streams, if their structure allows this;
      the automatic fall-back is to decompress and re-compress as before.

- Bugfix: Dangling font objects with non-replacable fonts (bug 311).

This also seems to be corrected; at least since then i didn't get such
dangling font objects. But i can't prove :-)

- Bugfix: cmap: unicode ???? is mapped to multiple glyphs (bug 306).

Here pdftex now reacts in a clear way (a warning?), Thanh can say what
that actually is :-) so one can consider this as closed...

Bug 320: this is the colorstack stuff. Maybe one should shift it into
"feature requests", it's documented, so it's no bug.

Bug 345: typo corrected by Pawe/l?

Bug 359: ???

Bug 362: a feature, not a bug.
