Constructor.
Create a new Game instance
- Parameters
-
| stage_width | Width of the game scene (unscaled). Fixed for the entire run time of the game. |
| stage_height | Height of the game scene (unscaled). Fixed for the entire run time of the game. |
| full_screen | Start in full screen or window mode. |
| target_fps | Target fps, usually 60 fps. |
| window_flags | Raylib window flags, preffered: GAME_CONFIG_FLAGS FLAG_WINDOW_RESIZABLE | FLAG_VSYNC_HINT | FLAG_MSAA_4X_HINT |
| exit_key | Game exit key. E.g. KEY_ESCAPE. Set it to KEY_NULL if the game app should not stop directly by pressing a key. |
| mouse | If true, the mouse position is available in game::core::Store::mouse_position. Please do not use the Raylib function GetMousePosition() which will not wok because of the scaling and letterboxing system. |
| audio | If true, Raylib will initialize the audio device. |
| project_name | Project name to be displayed as window title in Window mode. |

Starts the first game scene.
The method creates the main stage object of the game, which is accessible under game::core::Store::stage and transfers the scene object to the stage.
The method also implements the main game loop. In this, the contents of the current game scene are drawn via the stage object game::core::Store::stage.
Furthermore, the method increments the global game counter game::core::Store::ticks and updates the mouse pointer coordinates in game::core::Store::mouse_position if mouse support was enabled when instantiating the game object.
The method is also responsible for correctly scaling the displayed scene and inserting letterboxes if necessary to preserve the aspect ratio.
