3 * raylib v6.0 - 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, macOS, FreeBSD, Web, Android, Raspberry Pi, DRM native...
8 * - Written in plain C code (C99) in PascalCase/camelCase notation
9 * - Hardware accelerated with OpenGL (1.1, 2.1, 3.3, 4.3, ES2, ES3 - choose at compile)
10 * - Software renderer optional, for systems with no GPU: [rlsw]
11 * - Custom OpenGL abstraction layer (usable as standalone module): [rlgl]
12 * - Multiple Fonts formats supported (TTF, OTF, FNT, BDF, Sprite fonts)
13 * - Many texture formats supported, including compressed formats (DXT, ETC, ASTC)
14 * - Full 3d support for 3d Shapes, Models, Billboards, Heightmaps and more!
15 * - Flexible Materials system, supporting classic maps and PBR maps
16 * - Animated 3D models supported (skeletal bones animation) (IQM, M3D, GLTF)
17 * - Shaders support, including Model shaders and Postprocessing shaders
18 * - Powerful math module for Vector, Matrix and Quaternion operations: [raymath]
19 * - Audio loading and playing with streaming support (WAV, OGG, MP3, FLAC, QOA, XM, MOD)
20 * - VR stereo rendering with configurable HMD device parameters
21 * - Bindings to multiple programming languages available!
22 *
23 * NOTES:
24 * - One default Font is loaded on InitWindow()->LoadFontDefault() [core, text]
25 * - One default Texture2D is loaded on rlglInit(), 1x1 white pixel R8G8B8A8 [rlgl] (OpenGL 3.3 or ES2)
