 I don't think it'd need porting anyway, it's more or less Qt-independent code 
that operates on 2D array :). What's in Qt is the Imlib2/Mosfet scaling code 
(AKA fast), but there's still the ImageMagick-based scaling with very high 
quality. It's occasionally nice to have that one too, when doing large 
zooming, so I'd like to see Gwenview keeping it.
