/*******************************************************************************************
*
*   raylib [text] example - font spritefont
*
*   Example complexity rating: [★☆☆☆] 1/4
*
*   NOTE: Sprite fonts should be generated following this 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 by the same distance (margin/padding)
*     - Rectangles must be defined by a MAGENTA color background
*
*   Following those constraints, a font can be provided just by an image,
*   this is quite handy to avoid additional font descriptor files (like BMFonts use)
*
*   Example originally created with raylib 1.0, last time updated with raylib 1.0
*
*   Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
*   BSD-like license that allows static linking with closed source software
