Author: ray Date: Fri Mar 28 22:04:27 2014 New Revision: 263885 URL: http://svnweb.freebsd.org/changeset/base/263885 Log: o Add new vd_driver method to do bitblt with mask, named vd_maskbitbltchr. o Move vd_bitbltchr vga's driver method to vd_maskbitbltchr. o Implement new vd_bitbltchr method for vga driver. (It do single write for 8 pixels, have to be a bit faster).
