-This "bundled" freetype is built only in an Android build
-
 FreeType 2 is a software font engine that is designed to be small, efficient, highly customizable,
 and portable while capable of producing high-quality output (glyph images). It can be
 used in graphics libraries, display servers, font conversion tools, text image generation
 tools, and many other products as well.
