127.32L to me, beware when using git svn dcommit for committing stuff
to svn...

case where the source format is PIX_FMT_GRAY8.

This is required as PIX_FMT_GRAY8 has been declared as a paletted
format in FFmpeg r22191, fix GRAY8 -> RGB conversion.

format.

Make swscale-test only perform the test from the input to the output
format rather than perform all.

Also implement swscale-test-all.sh, for performing all the tests.

Improve flexibility of the swscale-test tool, this way is simpler to
perform only a subset of tests.

In particular fix the argb -> rgba and abgr -> bgra conversions.

in the isSupported{In,Out} macros. 

These pixel formats are not true pixel formats but hacks specific to
JPEG in libavcodec. They are deprecated and should be removed (that is
from libavcodec first and libswscale second)...  but they must be
tested by swscale-test.
