Font for DEC indicator panels

Actually, it turns out that only earlier panels (e.g. KA10, TC08, etc) use the
slashed zero; later ones (KI10, RP11, etc) use the ordinary ones. Since our
panel is intended for use with the RPV11-D, the unslashed is OK.


Thanks to all for all the help with the font; did anyone have any comments
on the _layout_ of the inlay (here:

for those who missed it among all the other messages).
