* Add a new GodotInstance GDCLASS that provides startup and iteration commands to control a Godot instance. * Adds a libgodot_create_godot_instance entry point that creates a new Godot instance and returns a GodotInstance object. * Adds a libgodot_destroy_godot_instance entry point that destroys the Godot instance. Sample Apps: https://github.com/migeran/libgodot_project Developed by [Migeran](https://migeran.com) Sponsors & Acknowledgements: * Initial development sponsored by [Smirk Software](https://www.smirk.gg/) * Rebasing to Godot 4.3 and further development sponsored by [Xibbon Inc.](https://xibbon.com) * The GDExtension registration of the host process & build system changes were based on @Faolan-Rad's LibGodot PR: https://github.com/godotengine/godot/pull/72883 * Thanks to Ben Rog-Wilhelm (Zorbathut) for creating a smaller, minimal version for easier review. * Thanks to Ernest Lee (iFire) for his support Co-Authored-By: Gabor Koncz <gabor.koncz@migeran.com> Co-Authored-By: Ben Rog-Wilhelm <zorba-github@pavlovian.net>
