We sorted out what 'vscan' means and are trying to use it correctly.
vscan = 0 is the same as vscan = 1, which is slightly annoying; we use MAX2(vscan, 1) everywhere.
randr doesn't pass vscan at all, so we set wsi mode vscan = 0.
The doublescan flag doubles the vscan value, so we don't need to deal with that separately, we can just compare flags normally.
