#### 7.2.114 set-motionscale

`(set-motionscale X)`
  Set the movimento scale factor to X (default value 0.5). These commands scale their movimento by an amount which depends on the distance from the frame to the center and on the size of the frame. Specifically, they scale by dist + scaleof(frame) * motionscale where dist is the distance from the center to the frame and motionscale is the movimento scale factor set by this function. Scaleof(frame) measures the size of the frame objeto.
