I assume what you mean is that the X server sans extensions and new libraries
doesn't do antialiased fonts.

Freetype became part of X some time ago, at least a couple of years now.

Or maybe you mean you have to use the Xft library.

That's true, but then really good font handling in X has always required
extra libraries because the font support was so bad for years

You can use Xft in all X apps because the server will fall back to character
cell and outline fonts if the Render extension is not available.

I don't know how it will look, but it will probably run well enough to keep
reminding you to upgrade.

Yep, that's basically it.

However, I didn't think Monaco had any pixels outside its bounding box.

I know two of the others I tried do though. You can see if you fire up a font

I generally do a terrible job working on fonts, at least so far.
