/** @file window.cpp Window manager. Window manager that manages a QWidget-based window.
* @ingroup base
*
* The Doomsday window management is responsible for the positioning, sizing,
* and state of the game's native windows. In practice, the code operates on Qt
* top-level windows.
*
* At the moment, the quality of the code is adequate at best. See the todo
* notes below for ideas for future improvements.
*
* @todo Instead of 'rect' and 'normalRect', the window should have a
* 'fullscreenSize' and a 'normalRect'. It isn't ideal that when toggling
* between fullscreen and windowed mode, the fullscreen resolution is chosen
* based on the size of the normal-mode window.
*
* @todo It is not a good idea to duplicate window state locally (position,
* size, flags). Much of the complexity here is due to this duplication, trying
* to keep all the state consistent. Instead, the real QWidget should be used
* for these properties. Qt has a mechanism for storing the state of a window:
* QWidget::saveGeometry(), QMainWindow::saveState().
*
* @todo Refactor for multiple window support. One window should be the "main"
* window while others are secondary windows.
*
* @todo Deferred window changes should be done using a queue-type solution
* where it is possible to schedule multiple tasks into the future separately
* for each window. Each window could have its own queue.
*
* @todo Platform-specific behavior should be encapsulated in subclasses, e.g.,
* MacWindowBehavior. This would make the code easier to follow and more adaptable
* to the quirks of each platform.
