Hello,

I'm attempting to extend the "Drawer" component found here:
http://kuwamoto.org/2006/05/11/example-code-updated-for-beta-3/

I've made changes so that:
A) it's a bottom-of-the-screen only component
B) it doesn't expand to the full width of the screen, only the width
of the Container it's in... this allows multiple drawers to be on the
screen.

Unfortunately, there's one thing I can't figure out.  The previous
code assumes that the parent will be the component that is
shown/hidden... However, if you have the Drawer attached to a
component nested deep down inside other components, you can't
determine if the parent component is really appearing on screen!

If I do the equivalent of "trace(parent.visible)" (in this code, it's
"realParent" not "parent"), it always appears true, even though the
TabNavigator is on a completely different tab.  How can I determine if
the parent component really is being displayed on the screen?
