It's not clear to me what you you think you are missing out on.
PDF is pretty much open.
You can get part of the way to where you want to go by using
affine transformations which is part of a published API.
The actual genie effect looks like morphing to me and lots has been written
about this.
It also looks like mapping of an image onto a surface which is the province of
OpenGL.
Its entirely possible that there is no API as such for this effect and that it is
simply
coded within the Finder.
I am not clear why it is called vector scaling since in actual fact bitmaps are
being scaled
in a non-linear fashion.
And while it may be frustrating I don't think its wise to insist dogmatically that
Apple
does not know what it is doing just because you cannot imagine a reason for their
actions.
Have Apple actually promised to open up an API for this??
