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.
