*
*   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)
