      This question boils down to the following:
      
      for each pixel in the picture
        set the pixel color to the matching tile pixel color
      
      What you have to be careful of is that the tile indices (x, y)
      must obey:
      
      x >= 0 && x < TILE_WIDTH
      y >= 0 && y < TILE_HEIGHT
        
      To find the indices of the matching tile pixel, you could use
      if statements. You could use the remainder operator instead;
      see Test2FShort.java
