This statement will shift the memory to the left by one position. Width specifies how many LED's , index inclusive, will take part in the shift operation.

When you shift information to the LEFT, the RIGHT-most LED will loose it's color information since it had no LED with data at the right.

Imagine 4 chairs with people on it. When they all stand up and go one place to the left, the person most left will have no chair to sit on. The chair on the right will be empty.
