But that is a faked rotation. The picture is (silently!) changed from 
linked to embedded. The rotation is not done by using a transformation 
but by generating a new picture.

The problem is not the rotation of the image (more exactly of the 
internal draw:frame element) itself. You can rotate Writer-kind images 
already be applying a transformation via macro.  But the missing part is 
to make the surrounding text consider the rotated image.
And in addition, there are bugs:
(1) The area of the bounding box, which is not covered by content is 
drawn wrongly. You see this bug already, when using negative crop values.
(2) Cropping does not work sufficient on rotated images.

That would be the wrong way. We would keep different kind of images. The 
better way is, to enhance the Draw-kind images to have all features of 
the Writer-kind images and then drop the Writer-kind images.

There is no need for a change in spec. The element draw:frame, which is 
used in Draw and Writer as well, has already an attribute draw:transform.

Kind regards
