Title: allow use of any Drawable for the errorDrawable

The code currently throws a `ClassCastException` if the `errorDrawable` is anything other than a `BitmapDrawable`, but there's no particular reason that I can see for this requirement. There are places in our UI where a `ColorDrawable` makes more sense; this patch fixes the issue.
