Do not scale \blur and \be when resampling

Resampling changes the PlayRes, not the LayoutRes, and \blur scales with
the LayoutRes.
(\be currently does not scale with *either* resolution, but libass
maintainers promise that *if* it ever scales with any resolution it will
scale with LayoutRes. Either way, it's not correct to scale it with
PlayRes.)
