Author: tsoome Date: Sun Jun 14 06:58:58 2020 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.
