65 * \brief Draw text to a window
66 * \param Window Destination Window
67 * \param X X coordinate (Left)
68 * \param Y Y coordinate (Top)
69 * \param W Width of destination region
70 * \param H Height of destination region
71 * \param Font Font to use
72 * \param Colour Text foreground colour
73 * \param Text UTF-8 string to render
74 * \param MaxLen Number of bytes in \a Text to read (Note: A final multi-byte sequence can exceed this count)
76 * \note As as noted in the \a MaxLen parameter, up to 3 more bytes may be read
77 * if the final character is a multi-byte UTF-8 sequence. This allows 1
78 * to be passed to only render a single character.
