When someone sets a sky.ColorFilter on either a ColorFilter widget or on an Image widget, we call operator== to check whether the filter has changed. If it has changed, we mark ourselves as needing paint. However, sky.ColorFilter doesn't implement operator==, which means we're just getting object identity, which means we're invalidating paint more often than necessary.
