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).
   

Can you describe what this does? From the commit message, it sounds like 
it might repair vt performance on cards with 8-bit framebuffers 
generally, but I can't figure out the code.
