/* Engine initialization
*
* Consists of several methods that are called by each platform's specific main(argc, argv).
* To fully understand engine init, one should therefore start from the platform's main and
* see how it calls into the Main class' methods.
*
* The initialization is typically done in 3 steps (with the setup2 step triggered either
* automatically by setup, or manually in the platform's main).
*
* - setup(execpath, argc, argv, p_second_phase) is the main entry point for all platforms,
* responsible for the initialization of all low level singletons and core types, and parsing
* command line arguments to configure things accordingly.
* If p_second_phase is true, it will chain into setup2() (default behaviour). This is
* disabled on some platforms (Android, iOS, UWP) which trigger the second step in their
* own time.
*
* - setup2(p_main_tid_override) registers high level servers and singletons, displays the
* boot splash, then registers higher level types (scene, editor, etc.).
*
* - start() is the last step and that's where command line tools can run, or the main loop
* can be created eventually and the project settings put into action. That's also where
* the editor node is created, if relevant.
* start() does it own argument parsing for a subset of the command line arguments described
* in help, it's a bit messy and should be globalized with the setup() parsing somehow.
