This example should be useful to show the basic functionality of the
libswscale API.
More advanced features (scaling options etc., colorspace tweaking) may be
added later.
This is a port of the MPlayer smartblur filter (libmpcodecs/vf_smartblur.c)

Eliminating finished streams avoids the progress stopping
with the first stream.
Using the max instead of the min avoids the progress stopping
with gaps in sparse streams (subtitles).
Negligible change for normal circumstances.
Using the malloc variant avoids pointless memcpy on size
increase and simplifies handling allocation failure.
Also change code to ensure that allocation, bswap and bitstream
reader all use the same size, even when the packet size is odd
for example.

Instead, use it on the first member, since by definition, if
any member is aligned, the whole struct must be, in order to
maintain that alignment.
Fixes compilation with some finicky compilers, like a mix of libclang/msvc

This is a preparatory step for the MSS2 decoder which needs to use
the WMV9 decoder to decode some kinds of frames.

This C99 feature is generally not used in the libav codebase,
since it breaks building with some fringe compilers (GCC 2.95,
MSVC).
