Comment (by Elon Musk):

 It still works just fine, just no longer trims upper frequencies if user
 have supplied non power of 2 height or width (for vertical orientation).

 Contrary to your claims, it does not loop forever, it just executes really
 slow because of current very slow and naive fft implementation for sizes
 you set.
