    // uploaded to the GPU, and discarded CPU-side. A dynamic texture is kept on
    // both the CPU and GPU, as it will likely be dynamically updated on the
    // CPU. A container texture exists only to keep the data on the CPU, usually
    // for later combination into a larger texture via the Stitcher class.
