Keys {@link Bitmap Bitmaps} using both {@link Bitmap#getAllocationByteCount()} and
the {@link Bitmap.Config} returned from {@link Bitmap#getConfig()}.

<p>
    Using both the config and the byte size allows us to safely re-use a greater variety of
    {@link Bitmap Bitmaps}, which increases the hit rate of the pool and therefore the performance
    of applications. This class works around #301 by only allowing re-use of {@link Bitmap Bitmaps}
    with a matching number of bytes per pixel.
