Use an 8bpp virtual device (instead of a 1bpp one) in sw and sc for iOS
The reason why a 1bpp virtual device is used in these two places in sc
and sw is unclear to me. It causes complications on iOS as such a
bitmap gets passed to CGBitmapContextCreate() which does not accept
1bpp bitmaps. But let's keep the 1bpp for other platforms.
