Ok, to address all comments I had and issues I've found (including issues I've
had with the extra plane), I've rewritten it a third time. This time I
basically integrate the tile format into the infrastructure adding
tile_width/tile_height to VideoFormatInfo, adding n_tiles_x, n_tiles_y to
VideoInfo (that get ajusted when gst_video_info_align() is called with
appropriate alignment). With this, I managed to implement generic frame copying
and generic color conversion for tiles. It should be really easy now to
implement a detiling fast-path (e.g. NV12_64x32 -> NV12, I420).
