New Revision: 362172
URL: https://svnweb.freebsd.org/changeset/base/362172
Log:
Move font related data structured to sys/font.c and update vtfontcvt
Prepare support to be able to handle font data in loader, consolidate
data structures to sys/font.h and update vtfontcvt.
vtfontcvt update is about to output set of glyphs in form of C source,
the implementation does allow to output compressed or uncompressed font
bitmaps.
