2*
3* raylib - A simple and easy-to-use library to enjoy videogames programming (www.raylib.com)
4*
5* FEATURES:
6* - NO external dependencies, all required libraries included with raylib
7* - Multiplatform: Windows, Linux, FreeBSD, OpenBSD, NetBSD, DragonFly, MacOS, UWP, Android, Raspberry Pi, HTML5.
8* - Written in plain C code (C99) in PascalCase/camelCase notation
9* - Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES2 - choose at compile)
10* - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
11* - Multiple Fonts formats supported (TTF, XNA fonts, AngelCode fonts)
12* - Outstanding texture formats support, including compressed formats (DXT, ETC, ASTC)
13* - Full 3d support for 3d Shapes, Models, Billboards, Heightmaps and more!
14* - Flexible Materials system, supporting classic maps and PBR maps
15* - Skeletal Animation support (CPU bones-based animation)
16* - Shaders support, including Model shaders and Postprocessing shaders
17* - Powerful math module for Vector, Matrix and Quaternion operations: [raymath]
18* - Audio loading and playing with streaming support (WAV, OGG, MP3, FLAC, XM, MOD)
19* - VR stereo rendering with configurable HMD device parameters
20* - Bindings to multiple programming languages available!
21*
22* NOTES:
23* One custom font is loaded by default when InitWindow() [core]
24* If using OpenGL 3.3 or ES2, one default shader is loaded automatically (internally defined) [rlgl]
25* If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
26*
