code: public void translate(double dx, double dy) {
  		this.m02 = this.m00 * dx + this.m01 * dy + this.m02;
  		this.m12 = this.m10 * dx + this.m11 * dy + this.m12;
  	}

  <p>This function is equivalent to:
  <pre>
  this = this *  [   1    0    dx   ]
  [   0    1    dy   ]
  [   0    0    1    ]
  </pre>
  
  @param dx the x translation
  @param dy the y translation
