Change: reworked how the Game Option display options are drawn
"Hardware acceleration" was not aligned with its checkbox. So instead
of drawing the labels left and the options right, now draw settings
one by one with a spacer between label and option to get the right
spacing.
Also, use SetPIP instead of repeating a SetPadding for all but
last element.
