scale works for me - aspect ratio has no effect?

are you sure this isnt something else?
have you checked your channel assignments?

but you cannot scale an image with keystone points and have the projection stay perspectively correct-

if you use submixes- you can scale an image - and it stays perspectively correct.

to use the building example again- if you set up a keystone mix to 4 corners of the facade of a building - you can move a layer around in xy and scale - and at every point it is perspectively correct.
the windows will line up.

what a keystone does is describe a plane- and how points are mapped from 2d space to projective 3d.
