Pre-multiply a translation to this matrix by translating by the given number of
units in x and y.
<p>
If <code>M</code> is <code>this</code> matrix and <code>T</code> the translation
matrix, then the new matrix will be <code>T * M</code>. So when
transforming a vector <code>v</code> with the new matrix by using
<code>T * M * v</code>, the translation will be applied last!
<p>
In order to set the matrix to a translation transformation without pre-multiplying
it, use {@link #translation(Vector2d)}.
@see #translation(Vector2d)
@param offset
the number of units in x and y by which to translate
@return this
