Let's do it.

Everybody with an XO can find at least a few kids. We need some images
of text, and a way to display them on all XOs. (B2-1 hardware too,
which normally runs build 406)

We'll need several languages. One of the CJK languages would be
particularly good to have; at one point Tux Paint had to localize
the font size for Japanese if I remember right.

Let's try several fonts. I find DejaVu to be somewhat difficult to
read because of the non-standard shapes. DejaVu appears to be much
worse for the African hooked characters, with defective line widths.

Reading speed and accuracy seem like the right metrics.

Both black-on-white and white-on-black should be tested.

Mono mode in very bright sunlight should be tested.

Consider line-to-line spacing separately.
