Subject: compensate for known terminal aspect ratio
X-Git-Url: http://git.shiar.nl/minime.git/commitdiff_plain/58ef2fa9c88f4bac0589cd85e580b92ec069e397?hp=10db3aab85650b4732a491621e99d487200931de

compensate for known terminal aspect ratio

Instead of assuming oldschool/high fonts, calculate from window resolution
and characters, supported by many terminals (at least urxvt, xterm, mlterm,
stterm, putty).

Depend on Term::ReadKey instead of calling a linux-specific ioctl, since
it's commonly installed already and obviously better for compatibility.
