Change the entire filter API to use reference counted images instead of vf_get_image(). Remove filter "direct rendering". This was useful for vf_expand and (in rare cases) vf_sub: DR allowed these filters to pass a cropped image to the filters before them. Then, on filtering, the image was "uncropped", so that black bars could be added around the image without copying. This means that in some cases, vf_expand will be slower (-vf gradfun,expand for example). Note that another form of DR used for in-place filters has been replaced by simpler logic. Instead of trying to do DR, filters can check if the image is writeable (with mp_image_is_writeable()), and do true in-place if that's the case. This affects filters like vf_gradfun and vf_sub. Everything has to support strides now. If something doesn't, making a copy of the image data is required.
