[ AS3] Masking Dynamic Content TextField and cacheAsBitmap

Ok, this is a quick post.

In a little project I am working right now I had to do some effects involving some textfield masking.  The problem I had is that the text was never masked and it always was visible on the display list. To solve this problem I had to use the cacheAsBitmap propriety of display objects. Once I set that to true everything went smooth.
