[Python-3000] PyGUI in Py3K stdlib, more details

[Jim Jewett]

Many of these issues have already been discussed -- and solved -- in a
web context, if you look at the w3c.org accessibility documents.

Exactly.

Only a tiny fraction of GUI applications (let alone applications which
happen to be coded with a GUI) actually require a pointing device for
functionality.  In practice, many require it anyway because of lazy
coding.  A standard library should support and encourage *best*
practices.

Bad idea.

The app may get ugly or require scrolling below a certain size, but it
should still work.

I've seen too many applications that can't be used because some
critical piece (usually "OK") is off the bottom of my screen, and the
application can't be resized.  (In the worst case, when I actually had
to use it, I reset my screen resolution to
unreadably-small-for-most-things, reboot, and then start over.)

Using even a bizarre order is still better than not offering the
navigation at all.
