## *.fnt

These are simple ASCII files. Here's an extract from `basfnt12.fnt`:

```
basfnt12.spr

r  65  90   0  25  A-Z
r  97 122  26  51  a-z
r  48  57  52  61  0-9
v  63      62      ?
# ...

done
```

The first line references a `.spr` file to read from. Then we have a list of
records that must specify mappings of ASCII -> glyphs.

First guess at the format:

* `r | v` is `range` vs. `value`
* Next we have the starting ASCII code
* For `r`, we now have the finishing ASCII code
* Next we have the starting position in the `.spr` file
* For `r`, we now have the finishing position in the `.spr` file
* Finally, just a comment?

Assuming that's all true, `basfont12.fnt` has 86 entries. It looks like a normal
[`.obj`](obj.md) file with... 86 entries. Good enough for me!

There's also a `cboxfont` file, which seems to be junk. `cboxfont.spr` and
`cboxfont.fmt` exist anyway. But who knows what else it might have in it.
