title: Slow motion tween text isn't smooth
body: <p>i have to create a movie where a text string move in horizontal.</p>
  
  <p>the problem is that in the movie (800px wide) the text should go from right to left in about 7 seconds (so it have to go about 400px to the left in 7 sec).</p>
  
  <p>i created a motion-tween with ease for my "text" and the tween is long (at 30fps) 30*7=210 frames.</p>
  
  <p>the result is that the text DON'T MOVE FLUID... it's not a uniform movement... it's too visible the fact that it moves X pixel each x frames. it's the exact opposite of SMOOTH MOVEMENT.</p>
  
  <p>How can i obtain a smooth slow-motion text movement?</p>
