You know that the size of the second \includegraphics with angle=45
is different?

The size of the second \includegraphics is a *square*. If w1 and h1
are the width and height of the first \includegraphics, then
the width w2 and h2 of the second \includegraphics with angle=45 are:

   w2 = h2 = sqrt(1/2) * (w1 + h1)

or
   w2 + h2
   ------- = sqrt(2) ≈ 1.4142
   w1 + h1
