Scale this image down to a specific size.
Returns a new image. Does not preserve aspect ratio.
nwidth and nheight are the new image's dimensions.
This method uses a fast integer algorithm where each source
pixel contributes to exactly one target pixel.
May give aliasing artifacts if new size is close to old size.
