Details:

The function imrotate presents a bad behaviour when using "Fourier"
parameter.

I've tried the 3.2.4 and 3.3.52 versions and the one that comes with ubuntu
10.04, all of them have the same bug. The following set of instructions cause
bad behaviour:

img = imread("myimg.jpg");
imgr = imrotate(img,65,"Fourier");

The rotated image is not properly working, I attach the result as an image.
