Scale this image down to fit within a specific size.
Returns a new image. The image's aspect ratio is preserved.
The image is scaled to the maximum possible size that fits
within the bounds specified by nwidth and nheight.
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.
