Hi,

Thanks Colin. I've updated grub-mkfont, main changes are:

* Include new tags FAMI, WEIG, SLAN, PTSZ
* Calculate font descent automatically. You can also overwrite it with
--desc option.
* Add option --force--autohint and --no-hinting
* Print font information in verbose mode.

level = 1 (-v): Print basic information, for example:
Font name: Arial Regular 16
Max width: 16
Max height: 15
Font ascent: 13
Font descent: 3
Number of glyph: 96

level >1 (-vv): Print basic information and ascii representation of
glyphs, for example:
Glyph #43, U+004b
Width 11, Height 12, X offset 0, Y offset 0, Device width 10

#: 1 in the bitmap
_: 0 in the bitmap
+: x, y axis
.: empty space inside (0, -desc, device_width, asce)
*: empty space outside (0, -desc, device_width, asce)

If there is no objection, I'd commit this patch in a few days.
