{
    SDL_BLENDOPERATION_ADD              = 0x1,  /**< dst + src: supported by all renderers */
    SDL_BLENDOPERATION_SUBTRACT         = 0x2,  /**< src - dst : supported by D3D9, D3D11, OpenGL, OpenGLES */
    SDL_BLENDOPERATION_REV_SUBTRACT     = 0x3,  /**< dst - src : supported by D3D9, D3D11, OpenGL, OpenGLES */
    SDL_BLENDOPERATION_MINIMUM          = 0x4,  /**< min(dst, src) : supported by D3D9, D3D11 */
    SDL_BLENDOPERATION_MAXIMUM          = 0x5   /**< max(dst, src) : supported by D3D9, D3D11 */
