MK - Lowpass filtering the glyphs in horizontal direction
Why the glyphs? Wouldn't you want to do that for everything that's
displayed?
Sure, if that's feasible to implement. Text is just the most interesting
and most radio-readable part
That's fun.
MK Sure, if that's feasible to implement.
Yes, it's easy. And it doesn't break the protocol.
Shadowfb, you introduce noise upon blasting to the real framebuffer.
Because, GetImage and friends work from the shadowfb, you're not
breaking the protocol.
You might actually end up with

Do we have any filtered Tempest fonts available for X.
BDF was not designed to carry gray-scale bitmap glyphs, as would be
necessary to display low-pass filtered fonts.
The X11 font system is in addition at present not capable to vary each

It's got something to do with deploying XFree86 in the American
