SDL: Allow window size to be reset whenever launcher is visible

This ensures the window gets resized properly when a user changes
the scaler options in the GUI. Simply unlocking the window size on
a call to setGraphicsMode is not good enough, because the scaler
mode can be changed by games during mode switches, and we don't
want to reset the window size in that case.
