- *  The required buffer size can be computed using cucul_get_font_width()
- *  and cucul_get_font_height().
- *
- *  This function never fails.
- *
- *  \param f The font, as returned by cucul_load_font()
- *  \param ch The character to render
- *  \param buf The image buffer
- *  \param stride width of the destination buffer
- *  \return This function always returns 0.
