/*******************************************************************************************
*
* raylib [text] example - Font loading
*
* raylib can load fonts from multiple file formats:
*
* - TTF/OTF > Sprite font atlas is generated on loading, user can configure
* some of the generation parameters (size, characters to include)
* - BMFonts > Angel code font fileformat, sprite font image must be provided
* together with the .fnt file, font generation cna not be configured
* - XNA Spritefont > Sprite font image, following XNA Spritefont conventions,
* Characters in image must follow some spacing and order rules
*
* This example has been created using raylib 2.6 (www.raylib.com)
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
