/**********************************************************************************************
*
* rcore - Window/display management, Graphic device/context management and input management
*
* PLATFORMS SUPPORTED:
* > PLATFORM_DESKTOP_GLFW (GLFW backend):
* - Windows (Win32, Win64)
* - Linux (X11/Wayland desktop mode)
* - macOS/OSX (x64, arm64)
* - FreeBSD, OpenBSD, NetBSD, DragonFly (X11 desktop)
* > PLATFORM_DESKTOP_SDL (SDL backend):
* - Windows (Win32, Win64)
* - Linux (X11/Wayland desktop mode)
* - Others (not tested)
* > PLATFORM_WEB:
* - HTML5 (WebAssembly)
* > PLATFORM_DRM:
* - Raspberry Pi 0-5 (DRM/KMS)
* - Linux DRM subsystem (KMS mode)
* > PLATFORM_ANDROID:
* - Android (ARM, ARM64)
*
* CONFIGURATION:
* #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, custom
*
* #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_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_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_AUTOMATION_EVENTS
* Support automatic events recording and playing, useful for automated testing systems or AI based game playing
*
* DEPENDENCIES:
* 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)
