characters % and @ have overlapping pixels

[robertmuth]

This piece config will avoid the overlap for % (and avoid the 7 "cheat" piece)

    (0, 6, 4, 16, 0),
    (2, 3, 0, 16, 0),
    (0, 0, 2, 13, 0),
    (2, 7, 4, 11, 2),
    (0, 2, 0, 10, 0)

Character will look slightly different:

**  **
**  * 
    * 
  **  
  **  
 *    
 *  **
**  **

This piece config will avoid the overlap for @:

    (6, 2, 1, 16, 0),
    (6, 1, 3, 16, 2),
    (1, 3, 0, 15, 0),
    (1, 4, 2, 13, 1),
    (2, 5, 0, 12, 2),
    (1, 2, 4, 12, 2),
    (0, 2, 2, 10, 2)

Character will look slightly different:

  **
