    ///
    /// The shape of the `TensorData` must be mappable to:
    /// - A `HxW` tensor, treated as a grayscale image.
    /// - A `HxWx3` tensor, treated as an RGB image.
    /// - A `HxWx4` tensor, treated as an RGBA image.
    ///
    /// Leading and trailing unit-dimensions are ignored, so that
    /// `1x640x480x3x1` is treated as a `640x480x3` RGB image.

    /// Since the underlying `rerun::datatypes::TensorData` uses `rerun::Collection` internally,
    /// data can be passed in without a copy from raw pointers or by reference from `std::vector`/`std::array`/c-arrays.
