Rotating a Bitmap on its' center (II)

Question

Hello,
I found this thread on the subject: http://forums.adobe.com/message/10208#10208
I have the exact same problem as the OP of that thread - my bitmaps rotate on their stage (x,y), not the center of the image, and seeing as that's a fairly old thread I wonder whether easier solutions has surfaced since then?
Thanks for your input.

the only cumbersome part is that you reference the parent, not the object to effectively change reg point.  so, if you have a displayobject dObj and you want to (apparently) change its reg point to x,y in the dObj coordinate space, you can specify the reference you want to use for the parent and use:
yourtransformedobject = regPointF("whateverreference",dObj,x,y);
yourtransformedobject = regPointF("whateverreference",dObj,dObj.width,0); // reg point at upper right
yourtransformedobject = regPointF("whateverreference",dObj,dObj.width,dObj.height);  // reg point at lower right
yourtransformedobject = regPointF("whateverreference",dObj,dObj.width/2,dObj.height/2);  // reg point at center
---------------------------------------------------------- this doesn't need to change -----------------------------------
var tl:MovieClip=this;
function regPointF(s:String,dObj,regX:Number,regY:Number):DisplayObjectContainer{
tl[s]=new DisplayObjectContainer();
tl[s].addChild(dObj);
dObj.x=-regX;
dObj.y=-regY;
return tl[s];
