I have found a couple of problems with the patch.
1. Try flipping an image 90 degrees in some direction and then hit reset. You
get a garbled preview image.
2. I get this warning when running ufraw: (ufraw:9964): Gtk-CRITICAL **:
gtk_adjustment_set_value: assertion `GTK_IS_ADJUSTMENT (adjustment)' failed
I have seen the doubled adjustment steps in the zoom adjustment. Try zooming to
50% using the 1:1 zoom button and then use the spinner to zoom out. It jumps to
48%. I think it is some sort of round-off error maybe in floor() but I have not
investigated it.
