When using higher resolutions in gfxterm, the default font is a bit
small. It looks like the default size grub-mkfont uses is 16, so I
tried rebuilding my own larger version of unicode.pf2 with --size=32.
It makes no difference. The output file is not any larger and when grub
loads it at boot time it looks exactly the same. I also tried
--size=64. I used /usr/share/fonts/X11/misc/unifont.pcf.gz as the grub
wiki suggests for the source.
