While these are all nice even values, would it make sense to test things 
with uneven sizes too?


This patch does seem good to me, however it does break the checkasm test 
on x86. Offhand I don't know where it differs between how swscale is used 
in reality (where I presume it does work just fine) and how it's set up in 
checkasm.
