/*
Overridable function, if necessary, for doing all of the drawing.
Base class version checks whether a redraw is needed and does nothing if not. See Redraw() function.
If a redraw is needed then there is an option to either redraw the whole screen or just redraw the moving objects.
If redrawing the whole screen then:
1a) SetupBackgroundBuffer is called to draw the background to the background buffer.
1b) DrawScreen is called to copy the background buffer onto the screen, then draw the moving objects.
1c) SDL_UpdateRect() is called to actually redraw the whole screen.
If only redrawing the moving objects then:
2a) DrawChangingObjects() is called to remove the objects from their old positions, and redraw them in their new positions.
2b) GetUpdateRectanglesForChangingObjects() is called to calculate where on the screen needs redrawing.
2c) SDL_UpdateRects() is called to redraw the parts of the screen which changed.
