Sculpt: Pose brush origin offset

With the previous behavior, it was impossible to manipulate areas with a lot of complex shapes like fingers, as the pose origin was calculated only with the topology inside the radius.
With pose offset, the previous method is used to calculate the direction of the "bone", and an extra offset is added on top of it. This way you can set the pose origin in the correct place in this kind of situations. The pose factor grows to fit the new rotation origin.
