Function scale2x_8_def

src/Engine/Scalers/scale2x.cpp:526–534

* Scale by a factor of 2 a row of pixels of 8 bits. * The function is implemented in C. * The pixels over the left and right borders are assumed of the same color of * the pixels on the border. * Note that the implementation is optimized to write data sequentially to * maximize the bandwidth on video memory. * \param src0 Pointer at the first pixel of the previous row. * \param src1 Pointer

 * \param dst1 Second destination row, double length in pixels.
