// arm NEON / C integer scalers for miyoomini
// args/ src : src offset address of top left corner
// dst : dst offset address of top left corner
// sw : src width pixels
// sh : src height pixels
// sp : src pitch (stride) bytes if 0, (src width * [2|4]) is used
// dp : dst pitch (stride) bytes if 0, (src width * [2|4] * multiplier) is used
//
// ** NOTE **
// since 32bit aligned addresses need to be processed for NEON scalers,
// x-offset and stride pixels must be even# in the case of 16bpp,
// if odd#, then handled by the C scaler
