/*******************************************************************************************
*
* raylib [text] example - Sprite font loading
*
* Loaded sprite fonts have been generated following XNA SpriteFont conventions:
* - Characters must be ordered starting with character 32 (Space)
* - Every character must be contained within the same Rectangle height
* - Every character and every line must be separated the same distance
* - Rectangles must be defined by a MAGENTA color background
*
* If following this constraints, a font can be provided just by an image,
* this is quite handy to avoid additional information files (like BMFonts use).
*
* This example has been created using raylib 1.0 (www.raylib.com)
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
