Function scale

src/Engine/Scalers/scalebit.cpp:480–502

* Apply the Scale effect on a bitmap. * This function is simply a common interface for ::scale2x(), ::scale3x() and ::scale4x(). * \param scale Scale factor. 2, 203 (fox 2x3), 204 (for 2x4), 3 or 4. * \param void_dst Pointer at the first pixel of the destination bitmap. * \param dst_slice Size in bytes of a destination bitmap row. * \param void_src Pointer at the first pixel of the source bit

 * \param height Vertical size in pixels of the source bitmap.
