* gst/videofilter/gstvideoflip.h: VideoFilter inherits from
BaseTransform, it's just a place holder for now and every video
effect plugin has been ported to use BaseTransform features
directly. QuarkTV was fixed too (was broken), navigationtest
works
and best for the end, videoflip converts navigation events
depending
on flip method ! Fixes #320953
