This might be a useful app. It's freeware from
http://pbone.it-mate.co.uk/pivot.htm
The application lets you create stick figures and then animate them. It's all 2d. It doesn't have any native stretch, squash, or foreshortening (although you can edit the figures). The animation does have onion skinning. You can also import a background image.
I think it might be useful for someone creating a figure to check that the body part lengths are good, or to try out a stance before making any pixels.
