Yes, but I also changed the signature of fill_line_with_color():

ff_fill_line_with_color(uint8_t *line[4], int pixel_step[4], int w,
                        uint8_t dst_color[4],
                        enum PixelFormat pix_fmt, uint8_t rgba_color[4],
                        int *is_packed_rgba, uint8_t rgba_map[4]);

by adding rgba_map (which is useful for the drawtext filter).
