From bd50862552f417f9d01d4a0d13ccc921ff26c5bf Mon Sep 17 00:00:00 2001
From: Andrew Robbins <contact@andrewrobbins.info>

Subject: Create grub-helper function grub_build_font

The idea is to build a font from source and then make a PF2 format
file from it using grub-mkfont.  This cuts down on the number of
binary files committed to history in the repository.
