        Make this match the Android icon exactly. Android adaptive icons take the inner (centered)
        2/3rds of the foreground's viewbox and crop out the rest [1].

        ic_foreground is at 1/2 scale and then cropped to 2/3rds of the original viewbox, so it
        takes up (1/2) / (2/3) = 3/4 of the cropped viewbox. In this SVG version, we don't crop.
        Instead, the full size icon is scaled down to 3/4 to match.
