/**********************************************************************************************
*
*   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 (deprecated - RPI OS Buster only)
*       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/
*       WARNING: This platform is deprecated, since RPI OS Bullseye, the old Dispmanx libraries are not
*       supported and you must be using PLATFORM_DRM
*
*   #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_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_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)
