*
*   raylib v5.5 - 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
