I found a way around that by using a container. I have an image
positioned absolute to top right inside container. this puts the lower
left corner of the image in center of container so that when container
is rotated with centerpoint as the axis, it looks like the image is
rotating from it's lower left corner.
I don't have practical examples to show, but that's something I tried
that worked in one instance. It's not perfect, but it's an idea that
could help someone else.
