    SDL_GPU_STENCILOP_ZERO,                 /**< Sets the value to 0. */
    SDL_GPU_STENCILOP_REPLACE,              /**< Sets the value to reference. */
    SDL_GPU_STENCILOP_INCREMENT_AND_CLAMP,  /**< Increments the current value and clamps to the maximum value. */
    SDL_GPU_STENCILOP_DECREMENT_AND_CLAMP,  /**< Decrements the current value and clamps to 0. */
    SDL_GPU_STENCILOP_INVERT,               /**< Bitwise-inverts the current value. */
    SDL_GPU_STENCILOP_INCREMENT_AND_WRAP,   /**< Increments the current value and wraps back to 0. */
