/// <summary>
/// Fractorium is the main window for the interactive renderer. The main viewable area
/// is a derivation of QGLWidget named GLWidget. The design uses the concept of a controller
/// to allow for both polymorphism and templating to coexist. Most processing functionality
/// is contained within the controller, and the GUI events just call the appropriate controller
/// member functions.
/// The rendering takes place on a timer with
/// a period of 0 which means it will trigger an event whenever the event input queue is idle.
/// As it's rendering, if the user changes anything on the GUI, a re-render will trigger. Since
/// certain parameters don't require a full render, the minimum necessary processing will be ran.
/// When the user changes something on the GUI, the required processing action is added to a vector.
/// Upon the next execution of the idle timer function, the most significant action will be extracted
/// and applied to the renderer. The state change vector is then cleared.
/// On the left side of the window is a dock widget which contains all controls needed for
/// manipulating embers. It's tabs can be floated, dragged, docked and nested elsewhere.
/// Qt takes very long to create file dialog windows, so they are kept as members and initialized
/// upon first use with lazy instantiation and then kept around for the remainder of the program.
/// Additional dialogs are for the about box, options, and final rendering out to a file.
/// While all class member variables and functions are declared in this .h file, the implementation
/// for them is far too lengthy to put in a single .cpp file. So general functionality is placed in
/// Fractorium.cpp and the other functional areas are each broken out into their own files.
/// The order of the functions in each .cpp file should roughly match the order they appear in the .h file.
/// Future todo list:
///		Implement more rendering types.
///		Add support for animation previewing.
///		Add support for full animation editing and rendering.
///		Possibly add some features from JWildFire.
