ShowBase: Minor fixes over aspect ratio and size calculations

Browse Source 
- Do not take into accound SBS if it is not enabled
        - Always return value for getSize()
        - Properly handle SBS for window-events
        - Redo positioning of aspect2d(p) markers exactly as
        they are created when adjusting aspect ratio
