*
* raylib v5.6-dev - A simple and easy-to-use library to enjoy videogames programming (www.raylib.com)
*
* FEATURES:
* - NO external dependencies, all required libraries included with raylib
* - Multiplatform: Windows, Linux, FreeBSD, OpenBSD, NetBSD, DragonFly,
* MacOS, Haiku, Android, Raspberry Pi, DRM native, HTML5.
* - Written in plain C code (C99) in PascalCase/camelCase notation
* - Hardware accelerated with OpenGL (1.1, 2.1, 3.3, 4.3, ES2, ES3 - choose at compile)
* - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
* - Multiple Fonts formats supported (TTF, OTF, FNT, BDF, Sprite fonts)
* - Outstanding texture formats support, including compressed formats (DXT, ETC, ASTC)
* - Full 3d support for 3d Shapes, Models, Billboards, Heightmaps and more!
* - Flexible Materials system, supporting classic maps and PBR maps
* - Animated 3D models supported (skeletal bones animation) (IQM, M3D, GLTF)
* - Shaders support, including Model shaders and Postprocessing shaders
* - Powerful math module for Vector, Matrix and Quaternion operations: [raymath]
* - Audio loading and playing with streaming support (WAV, OGG, MP3, FLAC, QOA, XM, MOD)
* - VR stereo rendering with configurable HMD device parameters
* - Bindings to multiple programming languages available!
*
* NOTES:
* - One default Font is loaded on InitWindow()->LoadFontDefault() [core, text]
* - One default Texture2D is loaded on rlglInit(), 1x1 white pixel R8G8B8A8 [rlgl] (OpenGL 3.3 or ES2)
