[flexcoders] Resizing an Image loaded at runtime

[fumeng5]

Hi -

I'm trying to resize an image when a user resizes a TitleWindow
component (I'm using a custom Sizeable TitleWindow component). 

I don't have a width or height set on my custom component but all
containers (children) have width and height set to 100%. I also have
scaleContent and maintainAspectRatio set to true. I think I have all
the pieces and am unsure why it still isn't resizing. Does anyone see
anything wrong with the code below?

Thanks in advance for taking a look,

Fumeng
