Third Code - Making the Cube Change as it Moves

The next step is to make the cube change as the mouse moved around. This was difficult is figure out but with a lot of experimenting I eventually got it.  I used a few lines of code from the tutorial from Ben Jack

  xpos = xpos + (mouseX-xpos)/30.0;

  ypos = ypos + (mouseY-ypos)/10.0;

i used this in the code. I then used xpos and ypos as coordinates for the box. because xpos and ypos are changing variables the box changed shape.
