[Tweener] x and y settings change during scaleX/Y Tween

[Gerry Creighton]

If you create the "images" yourself in Flash then you can manually  
change the registration point so that it is in the center.
If the images are placed on the stage dynamically or created  
dynamically their registration point will be at 0,0. To get them to
scale up so that they don't move to the right and down you should find  
a point to move the image to so that it moves from the
center of the image.
What I've done in the past is to create a couple of variables that  
calculates the x and y positions minus the amount you want
to scale the image to. You can then tween to those points for x and y.
You'll have to store the original x and y positions in variables to  
handle the rollOut.
I usually take the original x position and then subtract the image  
width divided by 2. The same for the y position.
In your tween you should be calling "onUpdate: function name" to check  
the location and size of the image you are scaling.
The function you call onUpdate will calculate where to move the image  
based on the original position minus it's current width/height.
On rollout just tween back to original x y and width height. I'll try  
to throw together an example if I get time.

Hope that helps.
