Add SWS_ACCURATE_RND to sws flags. Without this, conversions to RGB in
crop_scale_window_test leave the 6 pixels at the right side of the image
uninitialised (sws_scale doesn't fill them in with anything) so you get
garbage in the output. SWS_ACCURATE_RND fixes it. There are whisperings
that this is slow, so the impact of this patch may need to be measured
in some "real" situations.
