This makes no difference for supported input but avoids a
out of array read with input that is never passed in currently

if 0.0 != 0.0 a out of array read would occur, equal checks
with floating point may behave in such odd ways, though
this is very unlikely in a real implementation of a compiler

The DPX encoder now writes 12 DPX that open correctly (tested with
ImageMagick), and also correspond to the 12 bit sample files at
http://samples.ffmpeg.org/image-samples/dpx_samples.zipSigned-off-by: Michael Niedermayer <michaelni@gmx.at>

Rewrite the DPX decoder to work with provided sample DPXs at
http://samples.ffmpeg.org/image-samples/dpx_samples.zip

The decoder could only decode 8 and 10 bit without alpha correctly,
failing or even crashing at other flavors. This patch aims to fix
these issues, properly decoding all variants of DPX provided in the
referenced DPX sample zip. For 10 and 12 bit, the alpha channel
is ignored, but decoding is still possible.

We now only return in the middle of the refill in case of read error, so
inflate can be re-called if zlib needs an empty (z.avail_in=0) inflate
call for flushing.
