/**********************************************************************************************
*
* rcore - Basic functions to manage windows, OpenGL context and input on multiple platforms
*
* PLATFORMS SUPPORTED:
* - PLATFORM_DESKTOP: Windows (Win32, Win64)
* - PLATFORM_DESKTOP: Linux (X11 desktop mode)
* - PLATFORM_DESKTOP: FreeBSD, OpenBSD, NetBSD, DragonFly (X11 desktop)
* - PLATFORM_DESKTOP: OSX/macOS
* - PLATFORM_ANDROID: Android (ARM, ARM64)
* - PLATFORM_RPI: Raspberry Pi 0,1,2,3 (Raspbian, native mode)
* - PLATFORM_DRM: Linux native mode, including Raspberry Pi 4 with V3D fkms driver
* - PLATFORM_WEB: HTML5 with WebAssembly
*
* CONFIGURATION:
*
* #define PLATFORM_DESKTOP
* Windowing and input system configured for desktop platforms: Windows, Linux, OSX, FreeBSD, OpenBSD, NetBSD, DragonFly
* 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 in native mode (no XWindow required),
* graphic device is managed by EGL and inputs are processed is raw mode, reading from /dev/input/
*
* #define PLATFORM_DRM
* Windowing and input system configured for DRM native mode (RPI4 and other devices)
* 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 (rcamera.h) and multiple predefined cameras are available: free, 1st/3rd person, orbital
*
* #define SUPPORT_GESTURES_SYSTEM
* Gestures module is included (rgestures.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_TOUCH_AS_MOUSE
* Touch input and mouse input are shared. Mouse functions also return touch information.
*
* #define SUPPORT_SSH_KEYBOARD_RPI (Raspberry Pi only)
* Reconfigure standard input to receive key inputs, works with SSH connection.
* WARNING: Reconfiguring standard input could lead to undesired effects, like breaking other running processes or
* blocking the device if not restored properly. Use with care.
*
* #define SUPPORT_MOUSE_CURSOR_POINT
* Draw a mouse pointer on screen
*
* #define SUPPORT_BUSY_WAIT_LOOP
* Use busy wait loop for timing sync, if not defined, a high-resolution timer is setup and used
*
* #define SUPPORT_PARTIALBUSY_WAIT_LOOP
* Use a partial-busy wait loop, in this case frame sleeps for most of the time and runs a busy-wait-loop at the end
*
* #define SUPPORT_EVENTS_WAITING
* Wait for events passively (sleeping while no events) instead of polling them actively every frame
*
* #define SUPPORT_SCREEN_CAPTURE
* Allow automatic screen capture of current screen pressing F12, defined in KeyCallback()
*
* #define SUPPORT_GIF_RECORDING
* Allow automatic gif recording of current screen pressing CTRL+F12, defined in KeyCallback()
*
* #define SUPPORT_COMPRESSION_API
* Support CompressData() and DecompressData() functions, those functions use zlib implementation
* provided by stb_image and stb_image_write libraries, so, those libraries must be enabled on textures module
* for linkage
*
* #define SUPPORT_DATA_STORAGE
* Support saving binary data automatically to a generated storage.data file. This file is managed internally
*
* #define SUPPORT_EVENTS_AUTOMATION
* Support automatic generated events, loading and recording of those events when required
*
* DEPENDENCIES:
* rglfw - Manage graphic device, OpenGL context and inputs on PLATFORM_DESKTOP (Windows, Linux, OSX. FreeBSD, OpenBSD, NetBSD, DragonFly)
* raymath - 3D math functionality (Vector2, 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)
