I don't understand why you need to shuffle the input pixels with
SBUTTERFLY. Anyway, I feel uncomfortable being the only reviewer when
my reviews take like 2 minutes and are far from thorough.

Also, one last trick would be to use pmulhrw to perform the
rounding+shift in one instruction but that's, again, not something
worth more wait.
