(transform-incr objectID centerID frameID [rotate|translate|translate-scaled|scale] x y z [origin|bbox-center] [dt [smooth]])Apply continuing motion: construct a transformation matrix and
concatenate it with the current transform of objectID every
refresh (sets objectID’s incremental transform). Same syntax
as transform. If optional dt argument is present,
the object is moved at each time step such that its average motion
equals one instance of the motion per dt seconds. E.g.
(transform-incr World World World rotate 6.28318 0 0 10.0)
rotates the World about its X axis at 1 turn (2pi radians) per 10 seconds.
