-*
-* raylib.core - Basic functions to manage windows, OpenGL context and input on multiple platforms
-*
-* PLATFORMS SUPPORTED:
-* - Windows (win32/Win64)
-* - Linux (tested on Ubuntu)
-* - OSX (Mac)
-* - Android (ARM or ARM64)
-* - Raspberry Pi (Raspbian)
-* - HTML5 (Chrome, Firefox)
-*
-* CONFIGURATION:
-*
-* #define PLATFORM_DESKTOP
-* Windowing and input system configured for desktop platforms: Windows, Linux, OSX (managed by GLFW3 library)
-* NOTE: Oculus Rift CV1 requires PLATFORM_DESKTOP for mirror rendering - View [rlgl] module to enable it
-*
-* #define PLATFORM_ANDROID
-* Windowing and input system configured for Android device, app activity managed internally in this module.
-* NOTE: OpenGL ES 2.0 is required and graphic device is managed by EGL
-*
-* #define PLATFORM_RPI
-* Windowing and input system configured for Raspberry Pi (tested on Raspbian), graphic device is managed by EGL
-* and inputs are processed is raw mode, reading from /dev/input/
-*
-* #define PLATFORM_WEB
-* Windowing and input system configured for HTML5 (run on browser), code converted from C to asm.js
-* using emscripten compiler. OpenGL ES 2.0 required for direct translation to WebGL equivalent code.
-*
-* #define SUPPORT_DEFAULT_FONT (default)
-* Default font is loaded on window initialization to be available for the user to render simple text.
-* NOTE: If enabled, uses external module functions to load default raylib font (module: text)
-*
-* #define SUPPORT_CAMERA_SYSTEM
-* Camera module is included (camera.h) and multiple predefined cameras are available: free, 1st/3rd person, orbital
-*
-* #define SUPPORT_GESTURES_SYSTEM
-* Gestures module is included (gestures.h) to support gestures detection: tap, hold, swipe, drag
-*
-* #define SUPPORT_MOUSE_GESTURES
-* Mouse gestures are directly mapped like touches and processed by gestures system.
-*
-* #define SUPPORT_BUSY_WAIT_LOOP
-* Use busy wait loop for timming sync, if not defined, a high-resolution timer is setup and used
-*
-* #define SUPPORT_GIF_RECORDING
-* Allow automatic gif recording of current screen pressing CTRL+F12, defined in KeyCallback()
-*
-* DEPENDENCIES:
-* GLFW3 - Manage graphic device, OpenGL context and inputs on PLATFORM_DESKTOP (Windows, Linux, OSX)
-* raymath - 3D math functionality (Vector3, Matrix, Quaternion)
-* camera - Multiple 3D camera modes (free, orbital, 1st person, 3rd person)
-* gestures - Gestures system for touch-ready devices (or simulated from mouse inputs)

-/**********************************************************************************************
-*
-* raylib v1.8.0 stripped
-*
-* A simple and easy-to-use library to learn videogames programming (www.raylib.com)
-*
-* FEATURES:
-* - Library written in plain C code (C99)
-* - Multiple platforms supported: Windows, Linux, Mac, Android, Raspberry Pi, HTML5.
-* - Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES 2.0)
-* - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
-* - Powerful fonts module with SpriteFonts support (XNA bitmap fonts, AngelCode fonts, TTF)
-* - Multiple textures support, including compressed formats and mipmaps generation
-* - Basic 3d support for Shapes, Models, Billboards, Heightmaps and Cubicmaps
-* - Powerful math module for Vector2, Vector3, Matrix and Quaternion operations: [raymath]
-* - Audio loading and playing with streaming support and mixing channels: [audio]
-* - VR stereo rendering support with configurable HMD device parameters
-* - Minimal external dependencies (GLFW3, OpenGL, OpenAL)
-* - Complete bindings for Lua, Go and Pascal
-*
-* NOTES:
-* 32bit Colors - Any defined Color is always RGBA (4 byte)
-* 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:
-* GLFW3 (www.glfw.org) for window/context management and input [core]
-* GLAD for OpenGL extensions loading (3.3 Core profile, only PLATFORM_DESKTOP) [rlgl]
-* OpenAL Soft for audio device/context management [audio]
-*
-* OPTIONAL DEPENDENCIES:
-* stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA) [textures]
-* stb_image_write (Sean Barret) for image writting (PNG) [utils]
-* stb_truetype (Sean Barret) for ttf fonts loading [text]
-* stb_vorbis (Sean Barret) for ogg audio loading [audio]
-* jar_xm (Joshua Reisenauer) for XM audio module loading [audio]
-* jar_mod (Joshua Reisenauer) for MOD audio module loading [audio]
-* dr_flac (David Reid) for FLAC audio file loading [audio]
-* tinfl for data decompression (DEFLATE algorithm) [rres]

-*
-* raymath v1.1 - Math functions to work with Vector3, Matrix and Quaternions
-*
-* CONFIGURATION:
-*
-* #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_EXTERN_INLINE
-* Inlines all functions code, so it runs faster. This requires lots of memory on system.
-*
-* #define RAYMATH_STANDALONE
-* Avoid raylib.h header inclusion in this file.
-* Vector3 and Matrix data types are defined internally in raymath module.

-/**********************************************************************************************
-*
-* rlgl - raylib OpenGL abstraction layer
-*
-* rlgl is a wrapper for multiple OpenGL versions (1.1, 2.1, 3.3 Core, ES 2.0) to
-* pseudo-OpenGL 1.1 style functions (rlVertex, rlTranslate, rlRotate...).
-*
-* When chosing an OpenGL version greater than OpenGL 1.1, rlgl stores vertex data on internal
-* VBO buffers (and VAOs if available). It requires calling 3 functions:
-* rlglInit() - Initialize internal buffers and auxiliar resources
-* rlglDraw() - Process internal buffers and send required draw calls
-* rlglClose() - De-initialize internal buffers data and other auxiliar resources
-*
-* CONFIGURATION:
-*
-* #define GRAPHICS_API_OPENGL_11
-* #define GRAPHICS_API_OPENGL_21
-* #define GRAPHICS_API_OPENGL_33
-* #define GRAPHICS_API_OPENGL_ES2
-* Use selected OpenGL backend
-*
-* #define RLGL_STANDALONE
-* Use rlgl as standalone library (no raylib dependency)
-*
-* #define SUPPORT_VR_SIMULATOR
-* Support VR simulation functionality (stereo rendering)
-*
-* #define SUPPORT_DISTORTION_SHADER
-* Include stereo rendering distortion shader (shader_distortion.h)
-*
-* DEPENDENCIES:
-* raymath - 3D math functionality (Vector3, Matrix, Quaternion)
-* GLAD - OpenGL extensions loading (OpenGL 3.3 Core only)

-/**********************************************************************************************
-*
-* rlgl - raylib OpenGL abstraction layer
-*
-* rlgl is a wrapper for multiple OpenGL versions (1.1, 2.1, 3.3 Core, ES 2.0) to
-* pseudo-OpenGL 1.1 style functions (rlVertex, rlTranslate, rlRotate...).
-*
-* When chosing an OpenGL version greater than OpenGL 1.1, rlgl stores vertex data on internal
-* VBO buffers (and VAOs if available). It requires calling 3 functions:
-* rlglInit() - Initialize internal buffers and auxiliar resources
-* rlglDraw() - Process internal buffers and send required draw calls
-* rlglClose() - De-initialize internal buffers data and other auxiliar resources
-*
-* CONFIGURATION:
-*
-* #define GRAPHICS_API_OPENGL_11
-* #define GRAPHICS_API_OPENGL_21
-* #define GRAPHICS_API_OPENGL_33
-* #define GRAPHICS_API_OPENGL_ES2
-* Use selected OpenGL graphics backend, should be supported by platform
-* Those preprocessor defines are only used on rlgl module, if OpenGL version is
-* required by any other module, use rlGetVersion() tocheck it
-*
-* #define RLGL_STANDALONE
-* Use rlgl as standalone library (no raylib dependency)
-*
-* #define SUPPORT_VR_SIMULATION / SUPPORT_STEREO_RENDERING
-* Support VR simulation functionality (stereo rendering)
-*
-* #define SUPPORT_SHADER_DISTORTION
-* Include stereo rendering distortion shader (shader_distortion.h)
-*
-* DEPENDENCIES:
-* raymath - 3D math functionality (Vector3, Matrix, Quaternion)
-* GLAD - OpenGL extensions loading (OpenGL 3.3 Core only)
