/*********************************************************************************************
*
* raylib 1.0.4 (www.raylib.com)
*
* A simple and easy-to-use library to learn videogames programming
*
* Features:
* Library written in plain C code (C99)
* Uses C# PascalCase/camelCase notation
* Hardware accelerated with OpenGL 1.1
* Powerful fonts module with SpriteFonts support
* Basic 3d support for Shapes and Models
* Audio loading and playing
*
* Used external libs:
* GLFW3 (www.glfw.org) for window/context management and input
* stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC)
* OpenAL Soft for audio device/context management
* tinfl for data decompression (DEFLATE algorithm)
*
* Some design decisions:
* 32bit Colors - All defined color are always RGBA
* 32bit Textures - All loaded images are converted automatically to RGBA textures
* SpriteFonts - All loaded sprite-font images are converted to RGBA and POT textures
* One custom default font is loaded automatically when InitWindow()
