Sets the preferred format for {@link Bitmap}s decoded in this request. Defaults to
{@link DecodeFormat#PREFER_RGB_565}. This replaces any previous calls to {@link #imageDecoder(ResourceDecoder)},
{@link #videoDecoder(ResourceDecoder)}, {@link #decoder(ResourceDecoder)} and
{@link #cacheDecoder(ResourceDecoder)}} with default decoders with the appropriate
options set.

<p>
    Note - If using a {@link Transformation} that expect bitmaps to support transparency, this should always be
    set to ALWAYS_ARGB_8888. RGB_565 requires fewer bytes per pixel and is generally preferable, but it does not
    support transparency.
