Bend Skeletal animation

Is there a tool for bending an sprite using a skeleton, Spriter lets you import different images so you can create a full skeleton of it, but what I need is be able to bend the sprites around some pivot point This will be used for example in hair and cloth movements, also on small movements like idle animations.

Is there a way?

You can "skew" using Rojo's Paster plug, but thats about it.

Anything else would involve a webgl solution.

Thank you, I will give it a look
