I wonder if there should be an exception in here somewhere for
hardware pixelformats, there is no reason to assume the hardware
pointers passed in AVFrame would be aligned, and aligning them would
cause all sorts of crashes.
Best case from an API standpoint would be if av_frame_check_align can
just claim hardware frames are aligned, so users don't have to
replicate that check.
