Fix scaling ratios for 1.0-1.2 games.

Why did you shift the scaling ratios?
This broke proper compatibility with all games with previous XeSS versions.
1.3x scaling ratio cannot be selected in games that don't update their code.
76% resolution scale preset cannot be used anymore, only 67% resolution preset but the improvements that were made from 1.2 to 1.3 don't bridge this gap.
