#250 Virtual poseable figures

[William Kendrick]

Idea: Magic Tools that offer poseable figures that can be placed on the canvas as outlines/guides. The figures could include:
* mannequin (aka manikin aka lay figure) for drawing people & anthropomorphic characters
* human hand
* four-legged animal(s) for drawing cats, dogs, bears

It would need to be possible to position, rotate, and articulate the skeletons of the shapes, which would be done in 3D. Doing all this via the current Magic API may not be acheivable.
