[Haskell-cafe] rotate image

Thanks for your answers and your time, but I fear that I didn't described
the problem accurately enough.

The background is in the window created with gtk2hs (windowNew). It's just a
fixed layout (fixedNew):
  bg <- imageNewFromFile "bg.jpg"
  fixedPut fBox bg (0,0) 

If I now create the new image (with imageNewFromFile "my.png") with it's
alpha values, I can put it somewhere via fixedPut, and the other image is
just covered where it should be, but I can't rotate the image.

So cairo and the surface come into play. This works as well, the surface has
it's alpha values where it should, but a drawingArea created with
drawingAreaNew has a rectangular shape and a color. 
This is the problem.

best regards
