No. The library will return Z_VERSION_ERROR if you try to

That said, zlib has been stable for years. If you're just now

Try adding these to the project:
There would be a couple of ways that you could do it... you could
place your certificate in the System keychain and then add it so that
it can be read by your application anytime. This should work okay and
if you do this during installation, the user should only have to
authenticate then.

Is zlib in all versions of 10.4 and 10.5?
Will any version of zlib always uncompress something created with a

Then you definitely want to create your own NSBitmapImageRep — the
init method will give you total control over the pixel format. Then
you can lockFocus and draw whatever you want into it.
So I have created this:

Hi Trygve,
I don't you should override -value or anything like that. NSOnState

You should draw your pressed art if and only if -isHighlighted is true.
It's probably appropriate to subclass NSButtonCell for this and draw
