@defgroup freetype Drawing UTF-8 strings with freetype/harfbuzz

This modules is to draw UTF-8 strings with freetype/harfbuzz.

1. Install freetype2 and harfbuzz in your system.
2. Create FreeType2 instance with createFreeType2() function.
3. Load font file with loadFontData() function.
4. Draw text with putText() function.

- If thickness parameter is negative, drawing glyph is filled.
- If thickness parameter is positive, drawing glyph is outlined with thickness.
- If line_type parameter is 16(or CV_AA), drawing glyph is smooth.
