-*
-*   raylib - 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, UWP, Android, Raspberry Pi, HTML5.
-*       - Written in plain C code (C99) in PascalCase/camelCase notation
-*       - Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES2 - choose at compile)
-*       - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
-*       - Multiple Fonts formats supported (TTF, XNA fonts, AngelCode 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
-*       - Skeletal Animation support (CPU bones-based animation)
-*       - 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, XM, MOD)
-*       - VR stereo rendering with configurable HMD device parameters
-*       - Bindings to multiple programming languages available!
-*
-*   NOTES:
-*       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
-*
-*   DEPENDENCIES (included):
-*       [core] rglfw (github.com/glfw/glfw) for window/context management and input (only PLATFORM_DESKTOP)
-*       [rlgl] glad (github.com/Dav1dde/glad) for OpenGL 3.3 extensions loading (only PLATFORM_DESKTOP)

+*   raylib - 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, UWP, Android, Raspberry Pi, HTML5.
+*       - Written in plain C code (C99) in PascalCase/camelCase notation
+*       - Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES2 - choose at compile)
+*       - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
+*       - Multiple Fonts formats supported (TTF, XNA fonts, AngelCode fonts)
+*       - Outstanding texture formats support, including compressed formats (DXT, ETC, ASTC)
+*       - Full 3d support for 3d Shapes, Models, Billboards, Heightmaps and more!

+*
+*   #define RAYMATH_IMPLEMENTATION
+*       Generates the implementation of the library into the included file.
+*       If not defined, the library is in header only mode and can be included in other headers
+*       or source files without problems. But only ONE file should hold the implementation.
+*
+*   #define RAYMATH_HEADER_ONLY
+*       Define static inline functions code, so #include header suffices for use.
+*       This may use up lots of memory.
+*
+*   #define RAYMATH_STANDALONE
+*       Avoid raylib.h header inclusion in this file.
+*       Vector3 and Matrix data types are defined internally in raymath module.
