SDL: Set better default scaler for high-resolution games

Browse Source 
Now that we have higher scale factors than 3, it makes sense to try and
figure out a default scaler for high-resolution games that approximate
the window size of a low resolution game.

That also means that we are not necessarily restricted to the normal
scaler, since AdvMame has both 2x and 4x versions.
