StageResizeManager class

here is a class for repositioning assets when we resize the stage.
example:

StageResizeManager.addConstraint(clip,StageResizeManager.TOP,50);
//Will position clip at 50 pixels from the top of the stage

StageResizeManager.addConstraint(clip,StageResizeManager.CENTERX,0);
//Will position clip in the center on the x axis

StageResizeManager.addConstraint(clip,StageResizeManager.CENTERX,-clip.width/2);
//if the anchor point is on the top left of the clip (which is the default in flash) this will center the clip and shift the position of the half of the width of the clip to make it perfectly centered

StageResizeManager.addConstraint(clip,StageResizeManager.PERCENTY,33);
//this will position the clip at 33 percent on the y axis


The availables constraints which are defined as constants of the class are :
