-// Text
-//
-// NanoVG allows you to load .ttf files and use the font to render text.
-//
-// The appearance of the text can be defined by setting the current text style
-// and by specifying the fill color. Common text and font settings such as
-// font size, letter spacing and text align are supported. Font blur allows you
-// to create simple text effects such as drop shadows.
-//
-// At render time the font face can be set based on the font handles or name.
-//
-// Font measure functions return values in local space, the calculations are
-// carried in the same resolution as the final rendering. This is done because
-// the text glyph positions are snapped to the nearest pixels sharp rendering.
-//
-// The local space means that values are not rotated or scale as per the current
-// transformation. For example if you set font size to 12, which would mean that
-// line height is 16, then regardless of the current scaling and rotation, the
-// returned line height is always 16. Some measures may vary because of the scaling
-// since aforementioned pixel snapping.
-//
-// While this may sound a little odd, the setup allows you to always render the
-// same way regardless of scaling. I.e. following works regardless of scaling:
-//
-//		const char* txt = "Text me up.";
-//		nvgTextBounds(vg, x,y, txt, NULL, bounds);
-//		nvgBeginPath(vg);
-//		nvgRoundedRect(vg, bounds[0],bounds[1], bounds[2]-bounds[0], bounds[3]-bounds[1]);

-    sokol_app.h -- cross-platform application wrapper
-
-    Project URL: https://github.com/floooh/sokol
-
-    Do this:
-        #define SOKOL_IMPL or
-        #define SOKOL_APP_IMPL
-    before you include this file in *one* C or C++ file to create the
-    implementation.
-
-    In the same place define one of the following to select the 3D-API
-    which should be initialized by sokol_app.h (this must also match
-    the backend selected for sokol_gfx.h if both are used in the same
-    project):
-
-        #define SOKOL_GLCORE33
-        #define SOKOL_GLES3
-        #define SOKOL_D3D11
-        #define SOKOL_METAL
-        #define SOKOL_WGPU
-
-    Optionally provide the following defines with your own implementations:
-
-        SOKOL_ASSERT(c)     - your own assert macro (default: assert(c))
-        SOKOL_UNREACHABLE() - a guard macro for unreachable code (default: assert(false))
-        SOKOL_WIN32_FORCE_MAIN  - define this on Win32 to use a main() entry point instead of WinMain
-        SOKOL_NO_ENTRY      - define this if sokol_app.h shouldn't "hijack" the main() function
-        SOKOL_APP_API_DECL  - public function declaration prefix (default: extern)
-        SOKOL_API_DECL      - same as SOKOL_APP_API_DECL
-        SOKOL_API_IMPL      - public function implementation prefix (default: -)
-
-    Optionally define the following to force debug checks and validations
-    even in release mode:
-
-        SOKOL_DEBUG         - by default this is defined if _DEBUG is defined
-
-    If sokol_app.h is compiled as a DLL, define the following before
-    including the declaration or implementation:
-
-        SOKOL_DLL
-
-    On Windows, SOKOL_DLL will define SOKOL_APP_API_DECL as __declspec(dllexport)
-    or __declspec(dllimport) as needed.
-
-    On Linux, SOKOL_GLCORE33 can use either GLX or EGL.
-    GLX is default, set SOKOL_FORCE_EGL to override.
-
-    For example code, see https://github.com/floooh/sokol-samples/tree/master/sapp
-
-    Portions of the Windows and Linux GL initialization, event-, icon- etc... code
-    have been taken from GLFW (http://www.glfw.org/)
-
-    iOS onscreen keyboard support 'inspired' by libgdx.
-
-    Link with the following system libraries:
-
-    - on macOS with Metal: Cocoa, QuartzCore, Metal, MetalKit
-    - on macOS with GL: Cocoa, QuartzCore, OpenGL
-    - on iOS with Metal: Foundation, UIKit, Metal, MetalKit
-    - on iOS with GL: Foundation, UIKit, OpenGLES, GLKit
-    - on Linux with EGL: X11, Xi, Xcursor, EGL, GL (or GLESv2), dl, pthread, m(?)
-    - on Linux with GLX: X11, Xi, Xcursor, GL, dl, pthread, m(?)
-    - on Android: GLESv3, EGL, log, android
-    - on Windows with the MSVC or Clang toolchains: no action needed, libs are defined in-source via pragma-comment-lib
-    - on Windows with MINGW/MSYS2 gcc: compile with '-mwin32' so that _WIN32 is defined
-        - link with the following libs: -lkernel32 -luser32 -lshell32
-        - additionally with the GL backend: -lgdi32
-        - additionally with the D3D11 backend: -ld3d11 -ldxgi
-
-    On Linux, you also need to use the -pthread compiler and linker option, otherwise weird
-    things will happen, see here for details: https://github.com/floooh/sokol/issues/376
-
-    On macOS and iOS, the implementation must be compiled as Objective-C.
-
-    FEATURE OVERVIEW
-    ================
-    sokol_app.h provides a minimalistic cross-platform API which
-    implements the 'application-wrapper' parts of a 3D application:
-
-    - a common application entry function
-    - creates a window and 3D-API context/device with a 'default framebuffer'
-    - makes the rendered frame visible
-    - provides keyboard-, mouse- and low-level touch-events
-    - platforms: MacOS, iOS, HTML5, Win32, Linux/RaspberryPi, Android
-    - 3D-APIs: Metal, D3D11, GL3.2, GLES3, WebGL, WebGL2

-    STEP BY STEP
-    ============
-    --- Add a sokol_main() function to your code which returns a sapp_desc structure
-        with initialization parameters and callback function pointers. This
-        function is called very early, usually at the start of the
-        platform's entry function (e.g. main or WinMain). You should do as
-        little as possible here, since the rest of your code might be called
-        from another thread (this depends on the platform):
-
-            sapp_desc sokol_main(int argc, char* argv[]) {
-                return (sapp_desc) {
-                    .width = 640,
-                    .height = 480,
-                    .init_cb = my_init_func,
-                    .frame_cb = my_frame_func,
-                    .cleanup_cb = my_cleanup_func,
-                    .event_cb = my_event_func,
-                    ...
-                };
-            }
-
-        To get any logging output in case of errors you need to provide a log
-        callback. The easiest way is via sokol_log.h:
-
-            #include "sokol_log.h"
-
-            sapp_desc sokol_main(int argc, char* argv[]) {
-                return (sapp_desc) {
-                    ...
-                    .logger.func = slog_func,
-                };
-            }
-
-        There are many more setup parameters, but these are the most important.
-        For a complete list search for the sapp_desc structure declaration
-        below.
-
-        DO NOT call any sokol-app function from inside sokol_main(), since
-        sokol-app will not be initialized at this point.
-
-        The .width and .height parameters are the preferred size of the 3D
-        rendering canvas. The actual size may differ from this depending on
-        platform and other circumstances. Also the canvas size may change at
-        any time (for instance when the user resizes the application window,
-        or rotates the mobile device). You can just keep .width and .height
-        zero-initialized to open a default-sized window (what "default-size"
-        exactly means is platform-specific, but usually it's a size that covers
-        most of, but not all, of the display).
-
-        All provided function callbacks will be called from the same thread,
-        but this may be different from the thread where sokol_main() was called.
-
-        .init_cb (void (*)(void))
-            This function is called once after the application window,
-            3D rendering context and swap chain have been created. The
-            function takes no arguments and has no return value.
-        .frame_cb (void (*)(void))
-            This is the per-frame callback, which is usually called 60
-            times per second. This is where your application would update
-            most of its state and perform all rendering.
-        .cleanup_cb (void (*)(void))
-            The cleanup callback is called once right before the application
-            quits.
-        .event_cb (void (*)(const sapp_event* event))
-            The event callback is mainly for input handling, but is also
-            used to communicate other types of events to the application. Keep the
-            event_cb struct member zero-initialized if your application doesn't require
-            event handling.
-
-        As you can see, those 'standard callbacks' don't have a user_data
-        argument, so any data that needs to be preserved between callbacks
-        must live in global variables. If keeping state in global variables
-        is not an option, there's an alternative set of callbacks with
-        an additional user_data pointer argument:
-
-        .user_data (void*)
-            The user-data argument for the callbacks below
-        .init_userdata_cb (void (*)(void* user_data))
-        .frame_userdata_cb (void (*)(void* user_data))
-        .cleanup_userdata_cb (void (*)(void* user_data))
-        .event_userdata_cb (void(*)(const sapp_event* event, void* user_data))
-
-        The function sapp_userdata() can be used to query the user_data
-        pointer provided in the sapp_desc struct.
-
-        You can also call sapp_query_desc() to get a copy of the
-        original sapp_desc structure.
-
-        NOTE that there's also an alternative compile mode where sokol_app.h
-        doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY.
-
-    --- Implement the initialization callback function (init_cb), this is called
-        once after the rendering surface, 3D API and swap chain have been
-        initialized by sokol_app. All sokol-app functions can be called
-        from inside the initialization callback, the most useful functions
-        at this point are:
-
-        int sapp_width(void)
-        int sapp_height(void)
-            Returns the current width and height of the default framebuffer in pixels,
-            this may change from one frame to the next, and it may be different
-            from the initial size provided in the sapp_desc struct.
-
-        float sapp_widthf(void)
-        float sapp_heightf(void)
-            These are alternatives to sapp_width() and sapp_height() which return
-            the default framebuffer size as float values instead of integer. This
-            may help to prevent casting back and forth between int and float
-            in more strongly typed languages than C and C++.
-
-        double sapp_frame_duration(void)
-            Returns the frame duration in seconds averaged over a number of
-            frames to smooth out any jittering spikes.
-
-        int sapp_color_format(void)
-        int sapp_depth_format(void)
-            The color and depth-stencil pixelformats of the default framebuffer,
-            as integer values which are compatible with sokol-gfx's
-            sg_pixel_format enum (so that they can be plugged directly in places
-            where sg_pixel_format is expected). Possible values are:
-
-                23 == SG_PIXELFORMAT_RGBA8
-                28 == SG_PIXELFORMAT_BGRA8
-                42 == SG_PIXELFORMAT_DEPTH
-                43 == SG_PIXELFORMAT_DEPTH_STENCIL
-
-        int sapp_sample_count(void)
-            Return the MSAA sample count of the default framebuffer.
-
-        const void* sapp_metal_get_device(void)
-        const void* sapp_metal_get_renderpass_descriptor(void)
-        const void* sapp_metal_get_drawable(void)
-            If the Metal backend has been selected, these functions return pointers
-            to various Metal API objects required for rendering, otherwise
-            they return a null pointer. These void pointers are actually
-            Objective-C ids converted with a (ARC) __bridge cast so that
-            the ids can be tunnel through C code. Also note that the returned
-            pointers to the renderpass-descriptor and drawable may change from one
-            frame to the next, only the Metal device object is guaranteed to
-            stay the same.
-
-        const void* sapp_macos_get_window(void)
-            On macOS, get the NSWindow object pointer, otherwise a null pointer.
-            Before being used as Objective-C object, the void* must be converted
-            back with a (ARC) __bridge cast.
-
-        const void* sapp_ios_get_window(void)
-            On iOS, get the UIWindow object pointer, otherwise a null pointer.
-            Before being used as Objective-C object, the void* must be converted
-            back with a (ARC) __bridge cast.
-
-        const void* sapp_win32_get_hwnd(void)
-            On Windows, get the window's HWND, otherwise a null pointer. The
-            HWND has been cast to a void pointer in order to be tunneled
-            through code which doesn't include Windows.h.
-
-        const void* sapp_d3d11_get_device(void)
-        const void* sapp_d3d11_get_device_context(void)
-        const void* sapp_d3d11_get_render_target_view(void)
-        const void* sapp_d3d11_get_depth_stencil_view(void)
-            Similar to the sapp_metal_* functions, the sapp_d3d11_* functions
-            return pointers to D3D11 API objects required for rendering,
-            only if the D3D11 backend has been selected. Otherwise they
-            return a null pointer. Note that the returned pointers to the
-            render-target-view and depth-stencil-view may change from one
-            frame to the next!
-
-        const void* sapp_wgpu_get_device(void)
-        const void* sapp_wgpu_get_render_view(void)
-        const void* sapp_wgpu_get_resolve_view(void)
-        const void* sapp_wgpu_get_depth_stencil_view(void)
-            These are the WebGPU-specific functions to get the WebGPU
-            objects and values required for rendering. If sokol_app.h
-            is not compiled with SOKOL_WGPU, these functions return null.
-
-        const void* sapp_android_get_native_activity(void);
-            On Android, get the native activity ANativeActivity pointer, otherwise
-            a null pointer.
-
-    --- Implement the frame-callback function, this function will be called
-        on the same thread as the init callback, but might be on a different
-        thread than the sokol_main() function. Note that the size of
-        the rendering framebuffer might have changed since the frame callback
-        was called last. Call the functions sapp_width() and sapp_height()
-        each frame to get the current size.
-
-    --- Optionally implement the event-callback to handle input events.
-        sokol-app provides the following type of input events:
-            - a 'virtual key' was pressed down or released
-            - a single text character was entered (provided as UTF-32 code point)
-            - a mouse button was pressed down or released (left, right, middle)
-            - mouse-wheel or 2D scrolling events
-            - the mouse was moved
-            - the mouse has entered or left the application window boundaries
-            - low-level, portable multi-touch events (began, moved, ended, cancelled)
-            - the application window was resized, iconified or restored
-            - the application was suspended or restored (on mobile platforms)
-            - the user or application code has asked to quit the application
-            - a string was pasted to the system clipboard
-            - one or more files have been dropped onto the application window
-
-        To explicitly 'consume' an event and prevent that the event is
-        forwarded for further handling to the operating system, call
-        sapp_consume_event() from inside the event handler (NOTE that
-        this behaviour is currently only implemented for some HTML5
-        events, support for other platforms and event types will
-        be added as needed, please open a github ticket and/or provide
-        a PR if needed).
-
-        NOTE: Do *not* call any 3D API rendering functions in the event
-        callback function, since the 3D API context may not be active when the
-        event callback is called (it may work on some platforms and 3D APIs,
-        but not others, and the exact behaviour may change between
-        sokol-app versions).
-
-    --- Implement the cleanup-callback function, this is called once
-        after the user quits the application (see the section
-        "APPLICATION QUIT" for detailed information on quitting
-        behaviour, and how to intercept a pending quit - for instance to show a
-        "Really Quit?" dialog box). Note that the cleanup-callback isn't
-        guaranteed to be called on the web and mobile platforms.
-
-    MOUSE CURSOR TYPE AND VISIBILITY
-    ================================
-    You can show and hide the mouse cursor with
-
-        void sapp_show_mouse(bool show)
-
-    And to get the current shown status:
-
-        bool sapp_mouse_shown(void)
-
-    NOTE that hiding the mouse cursor is different and independent from
-    the MOUSE/POINTER LOCK feature which will also hide the mouse pointer when
-    active (MOUSE LOCK is described below).
-
-    To change the mouse cursor to one of several predefined types, call
-    the function:
-
-        void sapp_set_mouse_cursor(sapp_mouse_cursor cursor)
-
-    Setting the default mouse cursor SAPP_MOUSECURSOR_DEFAULT will restore
-    the standard look.
-
-    To get the currently active mouse cursor type, call:
-
-        sapp_mouse_cursor sapp_get_mouse_cursor(void)
-
-    MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE)
-    ================================================
-    In normal mouse mode, no mouse movement events are reported when the
-    mouse leaves the windows client area or hits the screen border (whether
-    it's one or the other depends on the platform), and the mouse move events
-    (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in
-    framebuffer pixels in the sapp_event items mouse_x and mouse_y, and
-    relative movement in framebuffer pixels in the sapp_event items mouse_dx
-    and mouse_dy.
-
-    To get continuous mouse movement (also when the mouse leaves the window
-    client area or hits the screen border), activate mouse-lock mode
-    by calling:
-
-        sapp_lock_mouse(true)
-
-    When mouse lock is activated, the mouse pointer is hidden, the
-    reported absolute mouse position (sapp_event.mouse_x/y) appears
-    frozen, and the relative mouse movement in sapp_event.mouse_dx/dy
-    no longer has a direct relation to framebuffer pixels but instead
-    uses "raw mouse input" (what "raw mouse input" exactly means also
-    differs by platform).
-
-    To deactivate mouse lock and return to normal mouse mode, call
-
-        sapp_lock_mouse(false)
-
-    And finally, to check if mouse lock is currently active, call
-
-        if (sapp_mouse_locked()) { ... }
-
-    On native platforms, the sapp_lock_mouse() and sapp_mouse_locked()
-    functions work as expected (mouse lock is activated or deactivated
-    immediately when sapp_lock_mouse() is called, and sapp_mouse_locked()
-    also immediately returns the new state after sapp_lock_mouse()
-    is called.
-
-    On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave
-    differently, as dictated by the limitations of the HTML5 Pointer Lock API:
-
-        - sapp_lock_mouse(true) can be called at any time, but it will
-          only take effect in a 'short-lived input event handler of a specific
-          type', meaning when one of the following events happens:
-            - SAPP_EVENTTYPE_MOUSE_DOWN
-            - SAPP_EVENTTYPE_MOUSE_UP
-            - SAPP_EVENTTYPE_MOUSE_SCROLL
-            - SAPP_EVENTTYPE_KEY_UP
-            - SAPP_EVENTTYPE_KEY_DOWN
-        - The mouse lock/unlock action on the web platform is asynchronous,
-          this means that sapp_mouse_locked() won't immediately return
-          the new status after calling sapp_lock_mouse(), instead the
-          reported status will only change when the pointer lock has actually
-          been activated or deactivated in the browser.
-        - On the web, mouse lock can be deactivated by the user at any time
-          by pressing the Esc key. When this happens, sokol_app.h behaves
-          the same as if sapp_lock_mouse(false) is called.
-
-    For things like camera manipulation it's most straightforward to lock
-    and unlock the mouse right from the sokol_app.h event handler, for
-    instance the following code enters and leaves mouse lock when the
-    left mouse button is pressed and released, and then uses the relative
-    movement information to manipulate a camera (taken from the
-    cgltf-sapp.c sample in the sokol-samples repository
-    at https://github.com/floooh/sokol-samples):
-
-        static void input(const sapp_event* ev) {
-            switch (ev->type) {
-                case SAPP_EVENTTYPE_MOUSE_DOWN:
-                    if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) {
-                        sapp_lock_mouse(true);
-                    }
-                    break;
-
-                case SAPP_EVENTTYPE_MOUSE_UP:
-                    if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) {
-                        sapp_lock_mouse(false);
-                    }
-                    break;
-
-                case SAPP_EVENTTYPE_MOUSE_MOVE:
-                    if (sapp_mouse_locked()) {
-                        cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f);
-                    }
-                    break;
-
-                default:
-                    break;
-            }
-        }
-
-    CLIPBOARD SUPPORT
-    =================
-    Applications can send and receive UTF-8 encoded text data from and to the
-    system clipboard. By default, clipboard support is disabled and
-    must be enabled at startup via the following sapp_desc struct
-    members:
-
-        sapp_desc.enable_clipboard  - set to true to enable clipboard support
-        sapp_desc.clipboard_size    - size of the internal clipboard buffer in bytes
-
-    Enabling the clipboard will dynamically allocate a clipboard buffer
-    for UTF-8 encoded text data of the requested size in bytes, the default
-    size is 8 KBytes. Strings that don't fit into the clipboard buffer
-    (including the terminating zero) will be silently clipped, so it's
-    important that you provide a big enough clipboard size for your
-    use case.
-
-    To send data to the clipboard, call sapp_set_clipboard_string() with
-    a pointer to an UTF-8 encoded, null-terminated C-string.
-
-    NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be
-    called from inside a 'short-lived event handler', and there are a few
-    other HTML5-specific caveats to workaround. You'll basically have to
-    tinker until it works in all browsers :/ (maybe the situation will
-    improve when all browsers agree on and implement the new
-    HTML5 navigator.clipboard API).
-
-    To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED
-    event in your event handler function, and then call sapp_get_clipboard_string()
-    to obtain the pasted UTF-8 encoded text.
-
-    NOTE that behaviour of sapp_get_clipboard_string() is slightly different
-    depending on platform:
-
-        - on the HTML5 platform, the internal clipboard buffer will only be updated
-          right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent,
-          and sapp_get_clipboard_string() will simply return the current content
-          of the clipboard buffer
-        - on 'native' platforms, the call to sapp_get_clipboard_string() will
-          update the internal clipboard buffer with the most recent data
-          from the system clipboard
-
-    Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event,
-    and then call sapp_get_clipboard_string() right in the event handler.
-
-    The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app
-    as follows:
-
-        - on macOS: when the Cmd+V key is pressed down
-        - on HTML5: when the browser sends a 'paste' event to the global 'window' object
-        - on all other platforms: when the Ctrl+V key is pressed down
-
-    DRAG AND DROP SUPPORT
-    =====================
-    PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5
-    and on the native desktop platforms (Win32, Linux and macOS) because
-    of security-related restrictions in the HTML5 drag'n'drop API. The
-    WASM/HTML5 specifics are described at the end of this documentation
-    section:
-
-    Like clipboard support, drag'n'drop support must be explicitly enabled
-    at startup in the sapp_desc struct.
-
-        sapp_desc sokol_main() {
-            return (sapp_desc) {
-                .enable_dragndrop = true,   // default is false
-                ...
-            };
-        }
-
-    You can also adjust the maximum number of files that are accepted
-    in a drop operation, and the maximum path length in bytes if needed:
-
-        sapp_desc sokol_main() {
-            return (sapp_desc) {
-                .enable_dragndrop = true,               // default is false
-                .max_dropped_files = 8,                 // default is 1
-                .max_dropped_file_path_length = 8192,   // in bytes, default is 2048
-                ...
-            };
-        }
-
-    When drag'n'drop is enabled, the event callback will be invoked with an
-    event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on
-    the application window.
-
-    After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the
-    number of dropped files, and their absolute paths by calling separate
-    functions:
-
-        void on_event(const sapp_event* ev) {
-            if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) {
-
-                // the mouse position where the drop happened
-                float x = ev->mouse_x;
-                float y = ev->mouse_y;
-
-                // get the number of files and their paths like this:
-                const int num_dropped_files = sapp_get_num_dropped_files();
-                for (int i = 0; i < num_dropped_files; i++) {
-                    const char* path = sapp_get_dropped_file_path(i);
-                    ...
-                }
-            }
-        }
-
-    The returned file paths are UTF-8 encoded strings.
-
-    You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path()
-    anywhere, also outside the event handler callback, but be aware that the
-    file path strings will be overwritten with the next drop operation.
-
-    In any case, sapp_get_dropped_file_path() will never return a null pointer,
-    instead an empty string "" will be returned if the drag'n'drop feature
-    hasn't been enabled, the last drop-operation failed, or the file path index
-    is out of range.
-
-    Drag'n'drop caveats:
-
-        - if more files are dropped in a single drop-action
-          than sapp_desc.max_dropped_files, the additional
-          files will be silently ignored
-        - if any of the file paths is longer than
-          sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8
-          encoding) the entire drop operation will be silently ignored (this
-          needs some sort of error feedback in the future)
-        - no mouse positions are reported while the drag is in
-          process, this may change in the future
-
-    Drag'n'drop on HTML5/WASM:
-
-    The HTML5 drag'n'drop API doesn't return file paths, but instead
-    black-box 'file objects' which must be used to load the content
-    of dropped files. This is the reason why sokol_app.h adds two
-    HTML5-specific functions to the drag'n'drop API:
-
-        uint32_t sapp_html5_get_dropped_file_size(int index)
-            Returns the size in bytes of a dropped file.
-
-        void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request)
-            Asynchronously loads the content of a dropped file into a
-            provided memory buffer (which must be big enough to hold
-            the file content)
-
-    To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED
-    event is received:
-
-        sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){
-            .dropped_file_index = 0,
-            .callback = fetch_cb
-            .buffer = {
-                .ptr = buf,
-                .size = sizeof(buf)
-            },
-            .user_data = ...
-        });
-
-    Make sure that the memory pointed to by 'buf' stays valid until the
-    callback function is called!
-
-    As result of the asynchronous loading operation (no matter if succeeded or
-    failed) the 'fetch_cb' function will be called:
-
-        void fetch_cb(const sapp_html5_fetch_response* response) {
-            // IMPORTANT: check if the loading operation actually succeeded:
-            if (response->succeeded) {
-                // the size of the loaded file:
-                const size_t num_bytes = response->data.size;
-                // and the pointer to the data (same as 'buf' in the fetch-call):
-                const void* ptr = response->data.ptr;
-            }
-            else {
-                // on error check the error code:
-                switch (response->error_code) {
-                    case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL:
-                        ...
-                        break;
-                    case SAPP_HTML5_FETCH_ERROR_OTHER:
-                        ...
-                        break;
-                }
-            }
-        }
-
-    Check the droptest-sapp example for a real-world example which works
-    both on native platforms and the web:
-
-    https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c
-
-    HIGH-DPI RENDERING
-    ==================
-    You can set the sapp_desc.high_dpi flag during initialization to request
-    a full-resolution framebuffer on HighDPI displays. The default behaviour
-    is sapp_desc.high_dpi=false, this means that the application will
-    render to a lower-resolution framebuffer on HighDPI displays and the
-    rendered content will be upscaled by the window system composer.
-
-    In a HighDPI scenario, you still request the same window size during
-    sokol_main(), but the framebuffer sizes returned by sapp_width()
-    and sapp_height() will be scaled up according to the DPI scaling
-    ratio.
-
-    Note that on some platforms the DPI scaling factor may change at any
-    time (for instance when a window is moved from a high-dpi display
-    to a low-dpi display).
-
-    To query the current DPI scaling factor, call the function:
-
-    float sapp_dpi_scale(void);
-
-    For instance on a Retina Mac, returning the following sapp_desc
-    struct from sokol_main():
-
-    sapp_desc sokol_main() {
-        return (sapp_desc) {
-            .width = 640,
-            .height = 480,
-            .high_dpi = true,
-            ...
-        };
-    }
-
-    ...the functions the functions sapp_width(), sapp_height()
-    and sapp_dpi_scale() will return the following values:
-
-    sapp_width:     1280
-    sapp_height:    960
-    sapp_dpi_scale: 2.0
-
-    If the high_dpi flag is false, or you're not running on a Retina display,
-    the values would be:
-
-    sapp_width:     640
-    sapp_height:    480
-    sapp_dpi_scale: 1.0
-
-    If the window is moved from the Retina display to a low-dpi external display,
-    the values would change as follows:
-
-    sapp_width:     1280 => 640
-    sapp_height:    960  => 480
-    sapp_dpi_scale: 2.0  => 1.0
-
-    Currently there is no event associated with a DPI change, but an
-    SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the
-    framebuffer size changing.
-
-    Per-monitor DPI is currently supported on macOS and Windows.
-
-    APPLICATION QUIT
-    ================
-    Without special quit handling, a sokol_app.h application will quit
-    'gracefully' when the user clicks the window close-button unless a
-    platform's application model prevents this (e.g. on web or mobile).
-    'Graceful exit' means that the application-provided cleanup callback will
-    be called before the application quits.
-
-    On native desktop platforms sokol_app.h provides more control over the
-    application-quit-process. It's possible to initiate a 'programmatic quit'
-    from the application code, and a quit initiated by the application user can
-    be intercepted (for instance to show a custom dialog box).
-
-    This 'programmatic quit protocol' is implemented through 3 functions
-    and 1 event:
-
-        - sapp_quit(): This function simply quits the application without
-          giving the user a chance to intervene. Usually this might
-          be called when the user clicks the 'Ok' button in a 'Really Quit?'
-          dialog box
-        - sapp_request_quit(): Calling sapp_request_quit() will send the
-          event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler
-          callback, giving the user code a chance to intervene and cancel the
-          pending quit process (for instance to show a 'Really Quit?' dialog
-          box). If the event handler callback does nothing, the application
-          will be quit as usual. To prevent this, call the function
-          sapp_cancel_quit() from inside the event handler.
-        - sapp_cancel_quit(): Cancels a pending quit request, either initiated
-          by the user clicking the window close button, or programmatically
-          by calling sapp_request_quit(). The only place where calling this
-          function makes sense is from inside the event handler callback when
-          the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received.
-        - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user
-          clicks the window's close button or application code calls the
-          sapp_request_quit() function. The event handler callback code can handle
-          this event by calling sapp_cancel_quit() to cancel the quit.
-          If the event is ignored, the application will quit as usual.
-
-    On the web platform, the quit behaviour differs from native platforms,
-    because of web-specific restrictions:
-
-    A `programmatic quit` initiated by calling sapp_quit() or
-    sapp_request_quit() will work as described above: the cleanup callback is
-    called, platform-specific cleanup is performed (on the web
-    this means that JS event handlers are unregisters), and then
-    the request-animation-loop will be exited. However that's all. The
-    web page itself will continue to exist (e.g. it's not possible to
-    programmatically close the browser tab).
-
-    On the web it's also not possible to run custom code when the user
-    closes a browser tab, so it's not possible to prevent this with a
-    fancy custom dialog box.
-
-    Instead the standard "Leave Site?" dialog box can be activated (or
-    deactivated) with the following function:
-
-        sapp_html5_ask_leave_site(bool ask);
-
-    The initial state of the associated internal flag can be provided
-    at startup via sapp_desc.html5_ask_leave_site.
-
-    This feature should only be used sparingly in critical situations - for
-    instance when the user would loose data - since popping up modal dialog
-    boxes is considered quite rude in the web world. Note that there's no way
-    to customize the content of this dialog box or run any code as a result
-    of the user's decision. Also note that the user must have interacted with
-    the site before the dialog box will appear. These are all security measures
-    to prevent fishing.
-
-    The Dear ImGui HighDPI sample contains example code of how to
-    implement a 'Really Quit?' dialog box with Dear ImGui (native desktop
-    platforms only), and for showing the hardwired "Leave Site?" dialog box
-    when running on the web platform:

-
-    FULLSCREEN
-    ==========
-    If the sapp_desc.fullscreen flag is true, sokol-app will try to create
-    a fullscreen window on platforms with a 'proper' window system
-    (mobile devices will always use fullscreen). The implementation details
-    depend on the target platform, in general sokol-app will use a
-    'soft approach' which doesn't interfere too much with the platform's
-    window system (for instance borderless fullscreen window instead of
-    a 'real' fullscreen mode). Such details might change over time
-    as sokol-app is adapted for different needs.
-
-    The most important effect of fullscreen mode to keep in mind is that
-    the requested canvas width and height will be ignored for the initial
-    window size, calling sapp_width() and sapp_height() will instead return
-    the resolution of the fullscreen canvas (however the provided size
-    might still be used for the non-fullscreen window, in case the user can
-    switch back from fullscreen- to windowed-mode).
-
-    To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen().
-
-    To check if the application window is currently in fullscreen mode,
-    call sapp_is_fullscreen().
-
-    WINDOW ICON SUPPORT
-    ===================
-    Some sokol_app.h backends allow to change the window icon programmatically:
-
-        - on Win32: the small icon in the window's title bar, and the
-          bigger icon in the task bar
-        - on Linux: highly dependent on the used window manager, but usually
-          the window's title bar icon and/or the task bar icon
-        - on HTML5: the favicon shown in the page's browser tab
-
-    NOTE that it is not possible to set the actual application icon which is
-    displayed by the operating system on the desktop or 'home screen'. Those
-    icons must be provided 'traditionally' through operating-system-specific
-    resources which are associated with the application (sokol_app.h might
-    later support setting the window icon from platform specific resource data
-    though).
-
-    There are two ways to set the window icon:
-
-        - at application start in the sokol_main() function by initializing
-          the sapp_desc.icon nested struct
-        - or later by calling the function sapp_set_icon()
-
-    As a convenient shortcut, sokol_app.h comes with a builtin default-icon
-    (a rainbow-colored 'S', which at least looks a bit better than the Windows
-    default icon for applications), which can be activated like this:
-
-    At startup in sokol_main():
-
-        sapp_desc sokol_main(...) {
-            return (sapp_desc){
-                ...
-                icon.sokol_default = true
-            };
-        }
-
-    Or later by calling:
-
-        sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true });
-
-    NOTE that a completely zero-initialized sapp_icon_desc struct will not
-    update the window icon in any way. This is an 'escape hatch' so that you
-    can handle the window icon update yourself (or if you do this already,
-    sokol_app.h won't get in your way, in this case just leave the
-    sapp_desc.icon struct zero-initialized).
-
-    Providing your own icon images works exactly like in GLFW (down to the
-    data format):
-
-    You provide one or more 'candidate images' in different sizes, and the
-    sokol_app.h platform backends pick the best match for the specific backend
-    and icon type.
-
-    For each candidate image, you need to provide:
-
-        - the width in pixels
-        - the height in pixels
-        - and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844
-          on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44)
-
-    For instance, if you have 3 candidate images (small, medium, big) of
-    sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup
-    like this:
-
-        // the actual pixel data (RGBA8, origin top-left)
-        const uint32_t small[16][16]  = { ... };
-        const uint32_t medium[32][32] = { ... };
-        const uint32_t big[64][64]    = { ... };
-
-        const sapp_icon_desc icon_desc = {
-            .images = {
-                { .width = 16, .height = 16, .pixels = SAPP_RANGE(small) },
-                { .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) },
-                // ...or without the SAPP_RANGE helper macro:
-                { .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } }
-            }
-        };
-
-    An sapp_icon_desc struct initialized like this can then either be applied
-    at application start in sokol_main:
-
-        sapp_desc sokol_main(...) {
-            return (sapp_desc){
-                ...
-                icon = icon_desc
-            };
-        }
-
-    ...or later by calling sapp_set_icon():
-
-        sapp_set_icon(&icon_desc);
-
-    Some window icon caveats:
-
-        - once the window icon has been updated, there's no way to go back to
-          the platform's default icon, this is because some platforms (Linux
-          and HTML5) don't switch the icon visual back to the default even if
-          the custom icon is deleted or removed
-        - on HTML5, if the sokol_app.h icon doesn't show up in the browser
-          tab, check that there's no traditional favicon 'link' element
-          is defined in the page's index.html, sokol_app.h will only
-          append a new favicon link element, but not delete any manually
-          defined favicon in the page
-
-    For an example and test of the window icon feature, check out the the
-    'icon-sapp' sample on the sokol-samples git repository.
-
-    ONSCREEN KEYBOARD
-    =================
-    On some platforms which don't provide a physical keyboard, sokol-app
-    can display the platform's integrated onscreen keyboard for text
-    input. To request that the onscreen keyboard is shown, call
-
-        sapp_show_keyboard(true);
-
-    Likewise, to hide the keyboard call:
-
-        sapp_show_keyboard(false);
-
-    Note that on the web platform, the keyboard can only be shown from
-    inside an input handler. On such platforms, sapp_show_keyboard()
-    will only work as expected when it is called from inside the
-    sokol-app event callback function. When called from other places,
-    an internal flag will be set, and the onscreen keyboard will be
-    called at the next 'legal' opportunity (when the next input event
-    is handled).
-
-    OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY)
-    ======================================================
-    In its default configuration, sokol_app.h "hijacks" the platform's
-    standard main() function. This was done because different platforms
-    have different main functions which are not compatible with
-    C's main() (for instance WinMain on Windows has completely different
-    arguments). However, this "main hijacking" posed a problem for
-    usage scenarios like integrating sokol_app.h with other languages than
-    C or C++, so an alternative SOKOL_NO_ENTRY mode has been added
-    in which the user code provides the platform's main function:
-
-    - define SOKOL_NO_ENTRY before including the sokol_app.h implementation
-    - do *not* provide a sokol_main() function
-    - instead provide the standard main() function of the platform
-    - from the main function, call the function ```sapp_run()``` which
-      takes a pointer to an ```sapp_desc``` structure.
-    - ```sapp_run()``` takes over control and calls the provided init-, frame-,
-      shutdown- and event-callbacks just like in the default model, it
-      will only return when the application quits (or not at all on some
-      platforms, like emscripten)
-
-    NOTE: SOKOL_NO_ENTRY is currently not supported on Android.
-
-    WINDOWS CONSOLE OUTPUT
-    ======================
-    On Windows, regular windowed applications don't show any stdout/stderr text
-    output, which can be a bit of a hassle for printf() debugging or generally
-    logging text to the console. Also, console output by default uses a local
-    codepage setting and thus international UTF-8 encoded text is printed
-    as garbage.
-
-    To help with these issues, sokol_app.h can be configured at startup
-    via the following Windows-specific sapp_desc flags:
-
-        sapp_desc.win32_console_utf8 (default: false)
-            When set to true, the output console codepage will be switched
-            to UTF-8 (and restored to the original codepage on exit)
-
-        sapp_desc.win32_console_attach (default: false)
-            When set to true, stdout and stderr will be attached to the
-            console of the parent process (if the parent process actually
-            has a console). This means that if the application was started
-            in a command line window, stdout and stderr output will be printed
-            to the terminal, just like a regular command line program. But if
-            the application is started via double-click, it will behave like
-            a regular UI application, and stdout/stderr will not be visible.
-
-        sapp_desc.win32_console_create (default: false)
-            When set to true, a new console window will be created and
-            stdout/stderr will be redirected to that console window. It
-            doesn't matter if the application is started from the command
-            line or via double-click.
-
-    MEMORY ALLOCATION OVERRIDE
-    ==========================
-    You can override the memory allocation functions at initialization time
-    like this:
-
-        void* my_alloc(size_t size, void* user_data) {
-            return malloc(size);
-        }
-
-        void my_free(void* ptr, void* user_data) {
-            free(ptr);
-        }
-
-        sapp_desc sokol_main(int argc, char* argv[]) {
-            return (sapp_desc){
-                // ...
-                .allocator = {
-                    .alloc = my_alloc,
-                    .free = my_free,
-                    .user_data = ...,
-                }
-            };
-        }
-
-    If no overrides are provided, malloc and free will be used.
-
-    This only affects memory allocation calls done by sokol_app.h
-    itself though, not any allocations in OS libraries.
-
-
-    ERROR REPORTING AND LOGGING
-    ===========================
-    To get any logging information at all you need to provide a logging callback in the setup call
-    the easiest way is to use sokol_log.h:
-
-        #include "sokol_log.h"
-
-        sapp_desc sokol_main(int argc, char* argv[]) {
-            return (sapp_desc) {
-                ...
-                .logger.func = slog_func,
-            };
-        }
-
-    To override logging with your own callback, first write a logging function like this:
-
-        void my_log(const char* tag,                // e.g. 'sapp'
-                    uint32_t log_level,             // 0=panic, 1=error, 2=warn, 3=info
-                    uint32_t log_item_id,           // SAPP_LOGITEM_*
-                    const char* message_or_null,    // a message string, may be nullptr in release mode
-                    uint32_t line_nr,               // line number in sokol_app.h
-                    const char* filename_or_null,   // source filename, may be nullptr in release mode
-                    void* user_data)
-        {
-            ...
-        }
-
-    ...and then setup sokol-app like this:
-
-        sapp_desc sokol_main(int argc, char* argv[]) {
-            return (sapp_desc) {
-                ...
-                .logger = {
-                    .func = my_log,
-                    .user_data = my_user_data,
-                }
-            };
-        }
-
-    The provided logging function must be reentrant (e.g. be callable from
-    different threads).
-
-    If you don't want to provide your own custom logger it is highly recommended to use
-    the standard logger in sokol_log.h instead, otherwise you won't see any warnings or
-    errors.
-
-
-    TEMP NOTE DUMP
-    ==============
-    - onscreen keyboard support on Android requires Java :(, should we even bother?
-    - sapp_desc needs a bool whether to initialize depth-stencil surface
-    - GL context initialization needs more control (at least what GL version to initialize)
-    - application icon
-    - the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy
-      at the latest but should do it earlier, in onStop, as an app is "killable" after onStop
-      on Android Honeycomb and later (it can't be done at the moment as the app may be started
-      again after onStop and the sokol lifecycle does not yet handle context teardown/bringup)

-    NOTE:
-
-    Q: Why not use CAMetalDrawable.presentedTime on macOS and iOS?
-    A: The value appears to be highly unstable during the first few
-    seconds, sometimes several frames are dropped in sequence, or
-    switch between 120 and 60 Hz for a few frames. Simply measuring
-    and averaging the frame time yielded a more stable frame duration.
-    Maybe switching to CVDisplayLink would yield better results.
-    Until then just measure the time.
