Changing the Wallpaper to Scaled in Ubuntu 13.04

After upgrading to Ubuntu 13.04, I lost the ability to scale the desktop background.  At first, I tried just saving the image at a different size, but it kept cropping it in ways I didn't like.

Solution was pretty simple (though it should have still been available in the UI):

gsettings set org.gnome.desktop.background picture-options "scaled"
