Bruce Evans aa24f48b36 Add files to help manage the (vga) syscons mouse cursor.
To mostly fix distortion of mouse cursors by non-square pixels, I
needed 8 variants of the same cursor shape for large fonts and
another 7 variants for small fonts.  Some variants are shared,
leaving only 13 variants in 26 glyphs altogether.  Keep these in
the BDF source file cursor.bdf.  cursor.bdf has another 5 unused
experimental cursors in 10 glyphs.  cursor.awk is a simple awk
script for converting this and similar bdf files into C declarations
for copying into scvgarndr.c.  syscons doesn't use any of this yet.

# $FreeBSD$
#
# awk script to convert a bdf file to C declarations in a form specialized
# for the mouse cursors in syscons/scvgarndr.c. Usage:
# awk -f thisfile < file.bdf < file.c
# The accompanying syscons mouse cursor bdf file has specialized comments
# which this script converts to details in the C declarations.
# This is not a general conversion utility, but produces reasonable output
# if the input is for a monospaced font of size between 9x16 and 16x16.
