/**
* \class CApplication
* \brief Main application
*
* This class is responsible for main application execution, including creating
* and handling main application window, receiving events, etc.
*
* It is a singleton class with only one instance that can be created.
*
* Creation of other main objects
*
* The class creates the only instance of CInstanceManager, CEventQueue, CEngine,
* CRobotMain and CSound classes.
*
* Window management
*
* The class is responsible for creating app window, setting and changing the video mode,
* setting the position of mouse and changing the cursor, grabbing and writing screenshots.
*
* Events
*
* Events are taken from SDL event queue and either handled by CApplication or translated
* to common events from src/common.h and pushed to global event queue CEventQueue.
* Joystick events are generated somewhat differently, by running a separate timer,
* polling the device for changes and synthesising events on change. It avoids flooding
* the event queue with too many joystick events and the granularity of the timer can be
* adjusted.
*
* The events are further handled in CRobotMain class.
*
