		Font data source, file or memory buffer.
	</brief_description>
	<description>
		Built-in text servers support font data sources of the following formats:
		- Bitmap fonts in the [url=https://www.angelcode.com/products/bmfont/]BMFont[/url] format. Handles [code].fnt, *.font[/code] fonts containing texture atlases. Non-scalable. Supports distance fields. Complex text shaping support is limited.
		- Dynamic fonts using the [url=https://www.freetype.org/]FreeType[/url] and [url=https://github.com/silnrsi/graphite/]Graphite[/url] library for rasterization. Handles [code]*.ttf, *.otf[/code] fonts. Scalable. Doesn't support distance fields. Supports complex text shaping and OpenType features.
