Kinematic Unit Simulation supports now position control with PID controller instead of instantly reaching the target

now a sequence of add clear add operations does not result in an empty layer (now the last add is executed)

Initial version of a RobotPoseUnit which can be used to move a robot in 6D (mainly useful in simulated worlds)

Notably it won't continue scrolling when the time is stopped

Scaling support for RobotStateComponent (also fixes issues with poses of scaled models in the world)
