FTGL is a free open source library to enable developers to use arbitrary
fonts in their OpenGL (www.opengl.org) applications.
Unlike other OpenGL font libraries FTGL uses standard font file formats
so doesn't need a preprocessing step to convert the high quality font data
into a lesser quality, proprietary format.
FTGL uses the Freetype (www.freetype.org) font library to open and 'decode'
the fonts. It then takes that output and stores it in a format most
efficient for OpenGL rendering.
