It depends on where you center the transformation. If you rotate the 
meshes around the look_at point you get focal blur.

I suspect based on my Towers scene moving the meshes based on the camera 
location you get less blurring in the distance. It makes sense because 
the angles created by two triangles in a mesh to a distance object is 
much smaller than the angle on a closer object.
