Example
It is possible to show one preview by putting the next piece all alone in a 2-row-high playfield above the main playfield.

For a 12-block-wide playfield as seen in Tetrinet, use tnetrow in place of pfrow. For 14 blocks, use qprow. For narrower diagrams with larger blocks, use width1row to width9row. For narrower diagrams with normal size blocks, use mrow1 to mrow9.
