Function scale2x_16_mmx

src/Engine/Scalers/scale2x.cpp:1340–1348

* Scale by a factor of 2 a row of pixels of 16 bits. * This function operates like scale2x_8_mmx() but for 16 bits pixels. * \param src0 Pointer at the first pixel of the previous row. * \param src1 Pointer at the first pixel of the current row. * \param src2 Pointer at the first pixel of the next row. * \param count Length in pixels of the src0, src1 and src2 rows. It must * be at least 8 a

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