@brief Get the PU linear position (i.e. the prismatic's extension)
When the axis is set, the current position of the attached bodies is examined and that position will be the zero position.
The position is the "oriented" length between the position = (Prismatic axis) dot_product [(body1 + offset) - (body2 + anchor2)]
