Some more changes:

     1. Fix auto-slice calculation, which Ben broke. :)
     2. Do not require that the application locks the buffer when
        issuing the "overlay alpha" command, since it doesn't actually
        need to read the shm buffer.
     3. Dropped the dirty flag; if there are any invalid_rects, we
        already know the buffer is dirty.
     4. More clearly documented the application's responsibility for the
        buffer's lock byte for each slave command in vf_overlay.txt.
     5. Added information about autoslicing to the documentation.
