commit c090b46eeadf2f4aa77e9fe4df1f53b1d5459708
Author: DJ Delorie <dj@xxxxxxxxxxx>
Commit: DJ Delorie <dj@xxxxxxxxxxx>

    Check for empty layers.
    
    If you have a four-layer board but the inner layers are empty, photo
    mode dies.  This checks for at least the more common case, but
    further work to protect against *any* empty layer is warranted.
