Subject: font8x8: Shrink font, compensate for base change
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=7d3eaa87a142188bd01fa8927aa47c810f4529b8;p=FUZIX.git

font8x8: Shrink font, compensate for base change

It's dumb having the small font 128 symbols long when the first 32 are
weird stuff. Make it 96, and shift by 32 chars when printing. Saves us 256
bytes
