Auto-Resizing and Centering your Content tutorial

I’ve just run through this tutorial and I’ve got my site centering in my browser as planned.

However when I resize my browser window the text (I’m using a pixel font) is going fuzzy.

Is there some way I can lock ‘centerRectangle’ to a rounded X and Y coordinate so that this doesn’t happen?

function init()
{
stage.align=StageAlign.TOP_LEFT;
stage.scaleMode=StageScaleMode.NO_SCALE;
 
stage.addEventListener(Event.RESIZE, updateSize);
stage.dispatchEvent(new Event(Event.RESIZE));
 
backgroundRectangle.x = 0;
backgroundRectangle.y = 0;
}

init();
 
function updateSize(e:Event)
{
//Set background's size
backgroundRectangle.width = stage.stageWidth;
backgroundRectangle.height = stage.stageHeight;
 
//center content
centerRectangle.x = stage.stageWidth/2 - centerRectangle.width/2;
centerRectangle.y = stage.stageHeight/2 - centerRectangle.height/2;
}
