Scaling layers in 1 dimension?

Just wondering if it's possible to have layers scale in just X or Y rather than both at the same time? For instance, having a layer with 100% X scale, and 50% Y scale. This would be handy for doing isometric things (since the Height in iso style is usually 50%), and would allow for things to be rotated properly.

We don't plan to support this. I can't remember off the top of my head, but various engine details get pretty complicated if you can do non-linear scaling.
