I think it makes more sense for this to extend ProgressBar, so that it's more
modular and requires only a single item in the view hierarchy to use. If you
need to put it inside a FrameLayout, fine, go for it, but it doesn't make sense
to tie the FrameLayout aspect to the delayed hide/show logic. That was
convenient for its use in EB, but it should be cleaned up now.

Done.
