/*
    This is the main executable, 
        the objective of this project is to recreate/decompile the original pubg lite launcher, 
        with the aim of being lighter/more portable/and more compatible, 
        without the need for the .net crap, 
        this code is being developed to work with Windows XP Service pack 3 and higher , Linux and Macos.


    the project is using CEF 2623 b1401 for windows systems, and CEF 2704 b1415 for linux and macos.

    This program is focused on opening on your potato, so do not use 3D web elements like css3d, webgl etc,
            because this program may be focused on working with coding in software mode, not on gpus

    why do you want it to work on windows xp?
        for experiments, and also good portability


    
    Note! The original launcher uses CEF 3578 b1870 so some features may not be available.
    
    cef libraries should be c only, 
        do not include c++ wrappers, they require boring libraries and use __stdcall differently than __cdecl

        you can code this program with c++, but do not include the cef c++ libraries.

    the code for this program must be written with C 89 or C++ 98, 
            for compatibility with other compilers, and for readability.

        avoid specific compiler calls.

        avoid compiler specific syntax

    the code will use doxygen, so document the implemented code well



    compatible compilers are Open Watcom 1.9, Visual Studio 2019/2022, clang for macos

    I won't have access to the mac, so I'll leave that in someone else's hands.



    maybe some original launcher implementations don't work on linux and macos, 
                    like hiding the launcher window and leaving an icon in the tray


    use or create abstractions so that the code is the same on multiple platforms

    The CEF localization files for macOS are messier and uglier, 
        if you want to use Xcode or Cocoa it will look like this, 
            if not we will use the manual loading method.


    Now an IMPORTANT note, 
        I put libcef 2623 as libcef_ in the include directory, 
            and I put libcef 2704 in its place, 
            in case the program presents any problem, 
            or some inclusion code for Windows gives problems, 
            just use a macro and include libcef_ in place of libcef : this feat was done by phikill
