In the previous beta, I could use both the DragManager and
NativeDragManager to handle dropping files into my app, or
dragging/dropping things within my app. It now looks like you get one
or the other. With the NativeDragManagerImpl, you don't get any
control over the alpha level of the dragProxy image. My air app used
to support dropping files from the desktop and also moving things
around internally with the flash drag manager, but now I'm stuck with
the crappy NativeDragManagerImpl for everything. I sure hope this
gets put back the way it was in Beta 2 before the final release. I
don't want one Impl or the other, I need BOTH.
