I was talking about the technical side, it can be done after the screen is
renderered. But yes, that's an API change. You are quite well placed to
know the API changes every single hour. So not a big deal if it is done
very soon.

Not at all, we don't even need to hide text cursors, just add one, it'll
be hidden by the hardware one. Generic, easy.

Yes, that was my idea too, and it seems that's the best one. Just let the
user deal with the cursor, so we can forget the previous block, we just
add a function to hide hardware cursor, and that's it.

Ok. So as I said, brightness/contrast makes a point, we need this. Inverse
video is not our business, let the user code what he want.

Feel free. I prepare my pig ascii'z ;)

Thanks for the comment \o/

Do you ever saw *any* linux box without either slang, ncurses, X11, or
opengl library installed ? Even busybox and stuff like this embbed slang.
But if you code it, don't complain about my future hacky-hacks for hurd
consoles, my syllable drivers, the psp output, etc ;)


So, what do we do about embbeded font ?
