#### 7.2.138 transform-incr

`(transform-incr objetoID centerID frameID [rotate|translate|translate-scaled|scale] x y z [origin|bbox-center] [dt [smooth]])`
  Apply continuing movimento: construct a matriz de transformação and concatenate it with the current transform of objetoID every refresh (sets objetoID's incremental transform). Same syntax as transform. If optional `dt` argumento is present, the objeto is moved at each time step such that its average movimento equals one instance do movimento 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.
