OS X crashes on this illegal read, though other operating systems don't
seem to mind. The nasty + 1 in this malloc makes sure there is always a byte
for that instruction to read safely.
+
+ Further to the above, valgrind is now telling me that ff_rgb24ToY_ssse3
+ over-reads by more then _avx. I can't follow the code to work out how much,
+ so I'll just over-allocate by 32 bytes and have done with it. Empirical
+ testing suggests that it works.
