// WARNING: When you get the "best" rotation and translation
// from the following function, you must wait until the piece has
// its origin at least as low as row 0 (zero) instead of its initial
// row -1 (negative one) if any rotations (1,2,3) are required.
// Perform all rotations, and then perform translations. This
// avoids the problem of getting the piece jammed on the sides
// of the board where rotation is impossible. ***
// Also, the following strategy does not take advantage of the
// possibility of using free-fall and future movements to
// slide under overhangs and fill them in.
