[#TODO]
  [ ] Base layer and OS abstraction for Windows. (Ryan's Win32 platform layer is ~2k lines of code.)
    • ryan uses os_thread_launch (CreateThread) /join (WaitForSingleObject+CloseHandle)/detach (CloseHandle ?? what type?)
    See: base_threads
    just implement the stuff we need for:
    He launches a bunch of async threads from `main_thread_base_entry_point`
    • Creating / destroying threads.
    • rdtsc for timing
    • Thread primitives (Mutex, Semaphore, etc.)
    • Thread Creation / Deletion
    [ ] CreateWindow and other Windows-specific features for handling messaging.
  [ ] Context should include links to other living thread data (+ save dead threads in debug mode)
  
  [ ] push_scratch() macro. (basically an auto_release_temp)
  [ ] Start removing irrelevant header files (for unity build system)
  
  [ ] ... Mouse / Keyboard inputs
  [*] This is the order I want to follow, because I need them in thread context.
    - Entry point(s) `Entry_Point_Main.cpp`
      -> We can have a lib_init() instead of a clear entry point for now.
      -> Switch from library to application once I add an entry point
      -> See how rjf abstracts his entry points for each platform with TCTX.

[Design Stuff]
  [ ] "Primary Thread" <- Main entry point thread
  [ ] "Secondary Thread" <- does all the heavy lifting for the first thread and synchronizes with the first.
    [ ] Tertiary threads (launched by secondary thread and awaiting work as assigned by Primary and Secondary threads)
  [ ] Multi-threaded by default with sync points
    [ ] Need bindings for Semaphore and Mutex
  [ ] Does calling SetProcessWorkingSetSize(.., -1, -1) cause the program to crash? Why tho.
    [ ] Maybe we just shouldn't do this?
    [ ] *our* program memory usage can be calculated by Stack Size + allocations from GPAllocator + allocations from arena.
  [ ] I want to be able to create new Windows (instances) of the program that can communicate with one another.
  I want one program to be the "Main" and always in-tray, and the others to be "child instances"
[TODO - Low priority]
    [ ] Fix implementation so all source is just in .cpp files (including templates), and auto-generate forward declares like Vjekoslav does.
    [ ] Implement Secure Arenas (with VirtualLock, wiping memory with RtlSecureZeroMemory)
    [ ] Way to serialize and deserialize settings in Text (I think using binary is a mistake here?).
[Project Ideas] - order of operations:
    [ ] Pushbullet replacement should make it easy to understand how data can be securely moved over the internet via a central server.
    [ ] Signal replacement 
    [ ](Graphics): How do I create a basic overlay that shows the time, date, cpu/gpu temps, frequency, memory usage all the time and responds to global hotkey to show more info
    
[Documentation Notes]
  Main inspirations for this codebase:
    (1) jonathan blow & jai compiler project
    (2) casey muratori and "handmade" approach to software
    (3) ryan fleury and raddebugger codebase
