    Richard, is it OK with you to keep the following features only for a
    proprietary platform (Cocoa) in the Emacs 23.1 release?

An incorrect implementation of stippling is somewhat of a bug,
but it might be better than no implementation of stippling.
Anyway, I don't see a reason to object that this is only on MacOS.

These are minor things, nothing to object to.

These too are rather minor, nothing to object to.
