* raylib v1.7.0
* raylib v1.8.0
*
* A simple and easy-to-use library to learn videogames programming (www.raylib.com)
*
* FEATURES:
* - Library written in plain C code (C99)
* - Uses PascalCase/camelCase notation
* - Written in plain C code (C99) in PascalCase/camelCase notation
* - Multiple platforms support: Windows, Linux, Mac, Android, Raspberry Pi and 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 Vector, Matrix and Quaternion operations: [raymath]
* - Outstanding texture formats support, including compressed formats (DXT, ETC, PVRT, ASTC)
* - Basic 3d support for Geometrics, Models, Billboards, Heightmaps and Cubicmaps
* - Flexible Materials system, supporting classic maps and PBR maps
* - Shaders support, including Model shaders and Postprocessing shaders
* - 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
* - Multiple platforms support: Windows, Linux, Mac, Android, Raspberry Pi, HTML5 and Oculus Rift CV1
* - Custom color palette for fancy visuals on raywhite background
* - Minimal external dependencies (GLFW3, OpenGL, OpenAL)
* - Complete bindings for Lua, Go and Pascal
* - Complete bindings to LUA (raylib-lua) and Go (raylib-go)
*
* NOTES:
* 32bit Colors - All defined color are always RGBA (struct Color is 4 byte)
* One custom default font could be loaded automatically when InitWindow() [core]
* 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
* If using OpenGL 3.3 or ES2, two default shaders could be loaded automatically (internally defined)
*
* DEPENDENCIES:
* GLFW3 (www.glfw.org) for window/context management and input [core]
