-1. [Download](https://ziglang.org/download/) Zig v0.15.2 (stable)
-2. Ensure Zig is on your PATH
-3. Navigate to our project's root directory
-4. Call `zig build`

-// Majora's Screensaver (expects zig v0.15.x)
-// @author: Abner Coimbre <abner@terminal.click>
-// @description: Sample C app for Windows, Mac & Linux. Adapted from floooh's sokol examples.
-
-// The goal is to demonstrate how to write a cross-platform native app/game in vanilla C, using only Zig to compile.
-
-// Single-Header Libraries:
-// - Sokol (https://github.com/floooh/sokol): Windowing, input, and/or graphics
-// - STB (https://github.com/nothings/stb): Loading images/assets
-
-// Instructions
-// ---
-// 1. Ensure Zig is on your PATH: download from https://ziglang.org/download
-// 2. Navigate to this project's folder
-// 3. Run the `zig build` command
-// 4. For a macOS App Bundle try `zig build bundle` instead
-// ---
-// You may now run the executable under zig-out/
-
-// The command `zig build` executes build() below. Learn more at https://zig.guide/

-    ========
-    sokol_glue.h provides glue helper functions between sokol_gfx.h and sokol_app.h,
-    so that sokol_gfx.h doesn't need to depend on sokol_app.h but can be
-    used with different window system glue libraries.
-
-    PROVIDED FUNCTIONS
-    ==================
-
-    sg_environment sglue_environment(void)
-
-        Returns an sg_environment struct initialized by calling sokol_app.h
-        functions. Use this in the sg_setup() call like this:
-
-        sg_setup(&(sg_desc){
-            .environment = sglue_environment(),
-            ...
-        });
-
-    sg_swapchain sglue_swapchain(void)
-
-        Returns an sg_swapchain struct initialized by calling sokol_app.h
-        functions. Use this in sg_begin_pass() for a 'swapchain pass' like
-        this:
-
-        sg_begin_pass(&(sg_pass){ .swapchain = sglue_swapchain(), ... });

-
-
-    OVERVIEW
-    ========
-    sokol_log.h provides a default logging callback for other sokol headers.
-
-    To use the default log callback, just include sokol_log.h and provide
-    a function pointer to the 'slog_func' function when setting up the
-    sokol library:
-
-    For instance with sokol_audio.h:
-
-        #include "sokol_log.h"
-        ...
-        saudio_setup(&(saudio_desc){ .logger.func = slog_func });
-
-    Logging output goes to stderr and/or a platform specific logging subsystem
-    (which means that in some scenarios you might see logging messages duplicated):
-
-        - Windows: stderr + OutputDebugStringA()
-        - macOS/iOS/Linux: stderr + syslog()
-        - Emscripten: console.info()/warn()/error()
-        - Android: __android_log_write()
-
-    On Windows with sokol_app.h also note the runtime config items to make
-    stdout/stderr output visible on the console for WinMain() applications
-    via sapp_desc.win32_console_attach or sapp_desc.win32_console_create,
-    however when running in a debugger on Windows, the logging output should
-    show up on the debug output UI panel.
-
-    In debug mode, a log message might look like this:
-
-        [sspine][error][id:12] /Users/floh/projects/sokol/util/sokol_spine.h:3472:0:
-            SKELETON_DESC_NO_ATLAS: no atlas object provided in sspine_skeleton_desc.atlas
-
-    The source path and line number is formatted like compiler errors, in some IDEs (like VSCode)
-    such error messages are clickable.
-
-    In release mode, logging is less verbose as to not bloat the executable with string data, but you still get
-    enough information to identify the type and location of an error:
-
-        [sspine][error][id:12][line:3472]
-
-    RULES FOR WRITING YOUR OWN LOGGING FUNCTION
-    ===========================================
-    - must be re-entrant because it might be called from different threads
-    - must treat **all** provided string pointers as optional (can be null)
-    - don't store the string pointers, copy the string data instead
-    - must not return for log level panic

-    sokol_time.h    -- simple cross-platform time measurement
-
-    Project URL: https://github.com/floooh/sokol
-
-    Do this:
-        #define SOKOL_IMPL or
-        #define SOKOL_TIME_IMPL
-    before you include this file in *one* C or C++ file to create the
-    implementation.
-
-    Optionally provide the following defines with your own implementations:
-    SOKOL_ASSERT(c)     - your own assert macro (default: assert(c))
-    SOKOL_TIME_API_DECL - public function declaration prefix (default: extern)
-    SOKOL_API_DECL      - same as SOKOL_TIME_API_DECL
-    SOKOL_API_IMPL      - public function implementation prefix (default: -)
-
-    If sokol_time.h is compiled as a DLL, define the following before
-    including the declaration or implementation:
-
-    SOKOL_DLL
-
-    On Windows, SOKOL_DLL will define SOKOL_TIME_API_DECL as __declspec(dllexport)
-    or __declspec(dllimport) as needed.
-
-    void stm_setup();
-        Call once before any other functions to initialize sokol_time
-        (this calls for instance QueryPerformanceFrequency on Windows)
-
-    uint64_t stm_now();
-        Get current point in time in unspecified 'ticks'. The value that
-        is returned has no relation to the 'wall-clock' time and is
-        not in a specific time unit, it is only useful to compute
-        time differences.
-
-    uint64_t stm_diff(uint64_t new, uint64_t old);
-        Computes the time difference between new and old. This will always
-        return a positive, non-zero value.
-
-    uint64_t stm_since(uint64_t start);
-        Takes the current time, and returns the elapsed time since start
-        (this is a shortcut for "stm_diff(stm_now(), start)")
-
-    uint64_t stm_laptime(uint64_t* last_time);
-        This is useful for measuring frame time and other recurring
-        events. It takes the current time, returns the time difference
-        to the value in last_time, and stores the current time in
-        last_time for the next call. If the value in last_time is 0,
-        the return value will be zero (this usually happens on the
-        very first call).
-
-    uint64_t stm_round_to_common_refresh_rate(uint64_t duration)
-        This oddly named function takes a measured frame time and
-        returns the closest "nearby" common display refresh rate frame duration
-        in ticks. If the input duration isn't close to any common display
-        refresh rate, the input duration will be returned unchanged as a fallback.
-        The main purpose of this function is to remove jitter/inaccuracies from
-        measured frame times, and instead use the display refresh rate as
-        frame duration.
-        NOTE: for more robust frame timing, consider using the
-        sokol_app.h function sapp_frame_duration()
-
-    Use the following functions to convert a duration in ticks into
-    useful time units:
-
-    double stm_sec(uint64_t ticks);
-    double stm_ms(uint64_t ticks);
-    double stm_us(uint64_t ticks);
-    double stm_ns(uint64_t ticks);
-        Converts a tick value into seconds, milliseconds, microseconds
-        or nanoseconds. Note that not all platforms will have nanosecond
-        or even microsecond precision.
-
-    Uses the following time measurement functions under the hood:
-
-    Windows:        QueryPerformanceFrequency() / QueryPerformanceCounter()
-    MacOS/iOS:      mach_absolute_time()
-    emscripten:     emscripten_get_now()
-    Linux+others:   clock_gettime(CLOCK_MONOTONIC)
