Thanks for the tip. I have some work to do on preserving aspect ratios
and adding the centering capability, but the basic idea seems to work.
I created a content holder UIComponent, which overrides invalidateSize
override public function invalidateSize():void
{
if (allowInvalidateSize)
super.invalidateSize();
}
In the parent, I set the flag before and after adjusting the scale.
Since the content holder is itself a custom class, I suppose it would
be a little cleaner to add a public method to the content holder that
would do the scaling.
Simple, but gets the job done.
