    plug-ins: the frame image in animation-play is always in RGB.
    
    We don't care what the original image type is, because non-RGB images
    (in particular indexed ones) render very badly.
    gimp_layer_new_from_drawable() will automatically convert the original
    layer's type to the destination image's type (RGB) while copying.
