Sizer based dialogs (like wxSingleChoiceDialog) are now forced to initially appear in the visible area of the display, relocating the dialog before display so that it fits within the display (if possible). If the dialog will not fit in the display area, it is shifted so that the top edge with the title bar is visible on the display
