    Resize an image of the given source type by the given ratios, properly handling GIF transparency, giving back the resized image and the new image format type that should be used.

    Resize an image of the given source type by the given ratios, properly handling GIF transparency, giving back the resized image and the new image format type that should be used.

    The image type might change if the input type is an indexed color model, because it is a hard problem to choose an optimized palette, and currently we don't. This function will return "png" as the new type in this case.

    If the input image is not using an indexed color model with transparency, then the target format and color model will be identical to the source.
