New Revision: 270589
URL: http://svnweb.freebsd.org/changeset/base/270589

Log:
  vt(4): The cursor coordinates are relative to the drawn area
  
  ... not the whole screen. Don't use font offsets in
  vt_mark_mouse_position_as_dirty().
  
  This fixes a bug where the mouse position wasn't marked as dirty when
  approaching the borders of the drawn area.
