This method is equivalent to calling: <code>translate(w-1-2*x, h-1-2*y, 0).scale(w, h, 1)</code>
<p>
If <code>M</code> is <code>this</code> matrix and <code>T</code> the created transformation matrix,
then the new matrix will be <code>M * T</code>. So when transforming a
vector <code>v</code> with the new matrix by using <code>M * T * v</code>, the
created transformation will be applied first!
@param x
the tile's x coordinate/index (should be in <code>[0..w)</code>)
@param y
the tile's y coordinate/index (should be in <code>[0..h)</code>)
@param w
the number of tiles along the x axis
@param h
the number of tiles along the y axis
@return this
