Maybe it follows the .rotate documentation a
little bit: "There will be newly uncovered areas
in the image. These will filled with either the 
current colorkey for the Surface, or the topleft
pixel value. (with the alpha channel zeroed out
if available)"

No such "(with the alpha channel zeroed out if 
available)" portion in the .rotozoom description
but maybe a good enough hint?

Did you try my test case?  Does nothing with
alpha as far as I know :-)
