/**********************************************************************************************
*
* raylib v1.7.0
*
* A simple and easy-to-use library to learn videogames programming (www.raylib.com)
*
* FEATURES:
* - Library written in plain C code (C99)
* - Multiple platforms supported: Windows, Linux, Mac, Android, Raspberry Pi, HTML5.
* - Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES 2.0)
* - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
* - Powerful fonts module with SpriteFonts support (XNA bitmap fonts, AngelCode fonts, TTF)
* - Multiple textures support, including compressed formats and mipmaps generation
* - Basic 3d support for Shapes, Models, Billboards, Heightmaps and Cubicmaps
* - Powerful math module for Vector2, Vector3, Matrix and Quaternion operations: [raymath]
* - Audio loading and playing with streaming support and mixing channels: [audio]
* - VR stereo rendering support with configurable HMD device parameters
* - Minimal external dependencies (GLFW3, OpenGL, OpenAL)
* - Complete bindings for Lua, Go and Pascal
*
* NOTES:
* 32bit Colors - Any defined Color is always RGBA (4 byte)
* One custom font is loaded by default when InitWindow() [core]
* If using OpenGL 3.3 or ES2, one default shader is loaded automatically (internally defined) [rlgl]
* If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
*
* DEPENDENCIES:
* GLFW3 (www.glfw.org) for window/context management and input [core]
* GLAD for OpenGL extensions loading (3.3 Core profile, only PLATFORM_DESKTOP) [rlgl]
* OpenAL Soft for audio device/context management [audio]
*
* OPTIONAL DEPENDENCIES:
* stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA) [textures]
* stb_image_write (Sean Barret) for image writting (PNG) [utils]
* stb_truetype (Sean Barret) for ttf fonts loading [text]
* stb_vorbis (Sean Barret) for ogg audio loading [audio]
* jar_xm (Joshua Reisenauer) for XM audio module loading [audio]
* jar_mod (Joshua Reisenauer) for MOD audio module loading [audio]
* dr_flac (David Reid) for FLAC audio file loading [audio]
* tinfl for data decompression (DEFLATE algorithm) [rres]
